CVE-2025-55125Network attack vector

Root code execution via malicious backup configuration

Published Jan 8, 2026 · Updated Jan 8, 2026

Command injection in Veeam Backup & Replication 13.0.0.4967 through 13.0.1.180 allows remote authenticated users to execute code as root. A crafted backup configuration file reaches an undisclosed command-processing path that executes attacker-controlled input with root privileges. Access requires the highly privileged Backup Operator or Tape Operator role, after which arbitrary commands run with full control of the server.
