Name of the Vulnerable Software and Affected Versions Velociraptor (affected versions not specified)
Description The gRPC API contains a flaw in the 'VFSGetBuffer' endpoint used for reading files from the datastore. The system employs a prefix check against a list of denied prefixes to prevent unauthorized access to sensitive files or other organizations. This check can be bypassed, enabling users to access restricted files. Specifically, a user with read permissions in the ROOT organization can gain unauthorized access to other organizations.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
