Attack profile from CVSS 3.1 · CNA. Fix status from CNA. Impact type from CWE-863.

Summary

Velociraptor from 0 before 0.77.3 uses the wrong permission check in SetClientMetadata, so a user with LABEL_CLIENTS permission can update the server metadata. The flaw is an incorrect authorization check (CWE-863). An attacker needs a low-privileged authenticated account on the server, and the impact is limited to integrity of server metadata, which is meant to be changed only by the server admin.

Description from the CNA

Velociraptor's SetClientMetadata used the wrong permission check to enforce setting metadata on the server. This allows a user with LABEL_CLIENTS permission to update the server metadata. Server metadata is often used to store site wide configuration data that should only be updated by the server admin.
