This can lead to an RCE. \n\n### Patches \n\nUpgrade to NeuVector [version 5.2.2](https://open-docs.neuvector.com/releasenotes/5x) or later and latest Helm chart (2.6.3+). \n+ In 5.2.2 the certificate for JWT-signing is created automatically by controller with validity of 90days and rotated automatically.\n+ Use Helm-based deployment/upgrade to 5.2.2 to generate a unique certificate for Manager, REST API, ahd registry adapter. Helm based installation/upgrade is required in order to automatically generate certificates upon initial installation and each subsequent upgrade. \n+ See [release notes](https://open-docs.neuvector.com/releasenotes/5x) for manual/yaml based deployment advice.\n+ 5.2.2 also implements additional protections against possible RCE for the feature of custom compliance scripts. \n\n### Workarounds \n\nUsers can replace the Manager & Controller certificate manually by following the instructions in documented [here](https://open-docs.neuvector.com/configuration/console/replacecert). However, upgrading to 5.2.2 and replacing Manager/REST API certificate is recommended to provide additional security enhancements to prevent possible attempted exploit and resulting RCE. See [release notes](https://open-docs.neuvector.com/releasenotes/5x) for additional details.\n\n### Credits \n\nThank you to [Dejan Zelic](https://dejandayoff.com/) at [Offensive Security](https://www.offsec.com/) for responsibly reporting this vulnerability. \n\n### For More Information \n\nView the NeuVector [Security Policy](https://github.com/neuvector/neuvector/security) \n\nGeneral NeuVector [documentation](https://open-docs.neuvector.com/) \n\n## Affected packages\n\n- `github.com/neuvector/neuvector < 0.0.0-20231003121714-be746957ee7c`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/neuvector/neuvector 0.0.0-20231003121714-be746957ee7c`","depth":"midnight","depthScore":52,"depthScoreParts":{"impact":52.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
