Description
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).

AI Powered Q&A
Can you explain this vulnerability to me?

CVE-2025-6264 is a privilege escalation vulnerability in Velociraptor involving the Admin.Client.UpdateClientConfig artifact. This artifact, used to update client configurations, did not enforce required high-level permissions, allowing users with the COLLECT_CLIENT permission (typically the Investigator role) to execute it on endpoints. This flaw enables arbitrary command execution and potential full takeover of the endpoint by hijacking privileged execution threads. [1]


How can this vulnerability impact me? :

If exploited, this vulnerability can allow an attacker with existing COLLECT_CLIENT permissions to execute arbitrary commands on an endpoint, potentially leading to full endpoint takeover. This compromises the confidentiality, integrity, and availability of the affected system, allowing unauthorized changes and control. [1]


How can this vulnerability be detected on my network or system? Can you suggest some commands?

Detection can be performed by running the Velociraptor artifact verifier to identify unintended privilege escalations in custom artifacts. Specifically, verifying the Admin.Client.UpdateClientConfig artifact for improper permission enforcement can help detect this vulnerability. [1]


What immediate steps should I take to mitigate this vulnerability?

Immediate mitigation steps include using the "basic artifacts" mechanism to restrict execution of dangerous artifacts and running the artifact verifier to detect and prevent privilege escalation issues. Additionally, ensure Velociraptor is updated to version 0.74.3 or later where this vulnerability is fixed. [1]
