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.
