JWT token compromise can allow malicious actions including Remote Code Execution (RCE)

Impact

A user can reverse engineer the JWT token (JSON Web Token) used in authentication for Manager and API access, forging a valid NeuVector Token to perform malicious activity in NeuVector. This can lead to an RCE.

Patches

Upgrade to NeuVector version 5.2.2 or later and latest Helm chart (2.6.3+).

• In 5.2.2 the certificate for JWT-signing is created automatically by controller with validity of 90days and rotated automatically.
• 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.
• See release notes for manual/yaml based deployment advice.
• 5.2.2 also implements additional protections against possible RCE for the feature of custom compliance scripts.

Workarounds

Users can replace the Manager & Controller certificate manually by following the instructions in documented here. 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 for additional details.
