Veeam has released key updates to tackle multiple vulnerabilities in its Backup & Replication (VBR) system, notably a critical remote code execution (RCE) vulnerability (CVE-2025-23121) affecting domain-joined installations. Both watchTowr and CodeWhite researchers highlighted that even low-complexity attacks by authenticated domain users could exploit this vulnerability. Organizations using VBR are urged to implement two-factor authentication and consider separate Active Directory configurations. Previous RCE issues have shown attackers targeting these systems to compromise data and interrupt recovery efforts, emphasizing the urgent security implications for users.
Veeam's critical vulnerability in Backup & Replication allows remote code execution by authenticated domain users, highlighting the need for stringent security measures.
