A vulnerability in Veeam Backup & Replication allows a low-privileged user to start an agent remotely in server mode and obtain credentials, effectively escalating privileges to system-level access. This allows the attacker to upload files to the server with elevated privileges. The vulnerability exists because remote calls bypass permission checks, leading to full system compromise.
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
