Symantec Backup Exec 11.0, 12.0, 12.5, 13.0, and 13.0 R2 does not validate identity information sent between the media server and the remote agent, which allows man-in-the-middle attackers to execute NDMP commands via unspecified vectors.

Security readout for executives and security teams

This flaw affects older Symantec Backup Exec deployments where the media server and remote agent do not properly verify identity information. An attacker positioned between those systems could impersonate traffic and issue NDMP commands. The main business concern is compromise of backup operations, especially in legacy environments still running these versions. Exposure is most likely in legacy Backup Exec environments that still run the named versions and allow media server-to-agent traffic across networks where interception is possible. Treat this as a legacy backup-infrastructure risk. Prioritize if vulnerable versions remain in production, because backup compromise can affect recovery readiness and operational resilience. Mitigation focus: Inventory Backup Exec media servers and remote agents for the named legacy versions.; Check Symantec advisory guidance for supported updates or replacement paths.; Retire unsupported Backup Exec versions where feasible..
