CVE-2024-40717Network attack vector

Elevated code execution via editable job scripts

Published Dec 4, 2024 · Updated Mar 13, 2025

Remote code execution in Veeam Backup & Replication 12.2.0.334 and earlier 12 builds allows remote authenticated users to run scripts. Users holding a Viewer or Operator role can update an existing job to reference a pre-job or post-job script on a network share, schedule it almost immediately, and have the backup server launch it as LocalSystem. The attacker needs an assigned limited role on the backup server; successful execution grants arbitrary LocalSystem code execution.
