CVE-2025-6264: Velociraptor priviledge escalation via UpdateConfig artifact

Noroxi assessment

Priority: Monitor (action score 22/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 63.6% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Rapid7 Velociraptor 0.74.3.

Low priority for now. Upgrade to Rapid7 Velociraptor 0.74.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Velociraptor allows collection of VQL queries packaged into Artifacts from endpoints. These artifacts can be used to do anything and usually run with elevated permissions.  To limit access to some dangerous artifact, Velociraptor allows for those to require high permissions like EXECVE to launch. The Admin.Client.UpdateClientConfig is an artifact used to update the client's configuration. This artifact did not enforce an additional required permission, allowing users with COLLECT_CLIENT permissions (normally given by the "Investigator" role) to collect it from endpoints and update the configuration. This can lead to arbitrary command execution and endpoint takeover. To successfully exploit this vulnerability the user must already have access to collect artifacts from the endpoint (i.e. have the COLLECT_CLIENT given typically by the "Investigator' role).
