Authentication Bypass by Capture-replay


Severity High
Score 9.8/10


KubeVela is an application delivery platform Users using KubeVela's VelaUX APIServer could be affected by an authentication bypass vulnerability. In KubeVela prior to versions 1.4.11 and 1.5.4, VelaUX APIServer uses the `PlatformID` as the signed key to generate the JWT tokens for users. Another API called `getSystemInfo` exposes the platformID. This vulnerability allows users to use the platformID to re-generate the JWT tokens to bypass the authentication. Versions 1.4.11 and 1.5.4 contain a patch for this issue.
