BackupPC 'ClientNameAlias()' Security Bypass Vulnerability

BackupPC is prone to a security-bypass vulnerability because it allows authenticated attackers to mimic other systems in a multiuser configuration.

Attackers may exploit the issue to back up (and restore) sensitive files, which can lead to a complete compromise of an affected computer.

BackupPC 3.1.0 is vulnerable; other versions may also be affected.
