Technical details
This is an authentication bypass / identity spoofing vulnerability in the Velociraptor GUI. An authenticated attacker can send a specially crafted request with the "Grpc-Metadata-USER" custom header to spoof the identity of another user, including administrators. The vulnerability allows privilege escalation from a low-privileged authenticated user to administrator level. The attack requires the attacker to already have valid authentication credentials and network access to the GUI. Velociraptor has released version 0.77.2 as a patch for this vulnerability.
