RCE as root in Veeam Backup & Replication via malicious backup configuration file

IdentifiersCVE-2025-55125CWE-94

CVE-2025-55125 is a high-severity vulnerability in Veeam Backup & Replication Version 13 affecting build 13.0.1.180 and earlier 13.x builds. The flaw allows a user assigned the Backup Operator or Tape Operator role to achieve remote code execution as root by creating a malicious backup configuration file. The issue is a privilege-boundary escape in which an operator-level user can supply crafted backup configuration data that is subsequently processed in a way that results in execution with root privileges on the backup server. Veeam stated that versions 12.x and older are not affected. The vulnerability was discovered through Veeam internal testing and fixed in build 13.0.1.1071.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows code execution as root on the Veeam backup server. In practice this can result in full compromise of the backup infrastructure, including takeover of the host, tampering with backup operations, arbitrary system changes, persistence, and use of the backup environment as a pivot point for further intrusion. Because backup infrastructure is highly sensitive, compromise may also facilitate disruption of recovery operations and broader enterprise impact.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict Backup Operator and Tape Operator assignments to trusted personnel only, tightly control who can create or modify backup configuration files, enforce least privilege and change control around backup configuration management, isolate the Veeam server from untrusted networks, require strong authentication including MFA for administrative access, and monitor audit logs and backup activity for unusual configuration changes or suspicious operator actions.

Remediation

Patch, then assume compromise.

Upgrade Veeam Backup & Replication Version 13 to build 13.0.1.1071 or later. The available content states that the vulnerability affects Version 13 build 13.0.1.180 and earlier, and that versions 12.x and older are not impacted. Apply Veeam's security update immediately and review vendor security guidance for any additional hardening steps associated with the release.
