Kerentanan Authentication Bypass Using an Alternate Path or Channel. Skor CVSS 3.1 6.8 (Medium) menurut rapid7.com.

Deskripsi (NVD)

The Velociraptor gRPC API has a VFSGetBuffer endpoint which allows reading files from the datastore. To prevent users from reading sensitive files or accessing other orgs, the requested path is prefix checked against a list of denied prefixes. This prefix check can be bypassed allowing a user to access usually denied files. If the user has read permission in the ROOT org, this allows access to other orgs, in which the user may not have permission.
