CVE-2025-59468 is a remote code execution vulnerability identified in Veeam Backup and Recovery version 13.0.0. The vulnerability arises from improper handling of the password parameter by the Backup Administrator interface, allowing an attacker with Backup Administrator privileges to send a maliciously crafted password parameter that triggers execution of arbitrary code as the 'postgres' user. The 'postgres' user typically has elevated privileges within the backup system's embedded PostgreSQL database, which manages backup metadata and configurations. Exploiting this vulnerability could allow an attacker to manipulate backup data, exfiltrate sensitive information, or disrupt backup and recovery operations. The CVSS v3.1 score of 9.0 reflects the critical nature of this flaw, with an attack vector over the network (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), no user interaction (UI:N), and a scope change (S:C) indicating that the vulnerability affects resources beyond the initially compromised component. The impact on confidentiality, integrity, and availability is high, as arbitrary code execution could lead to full system compromise or data loss. Although no public exploits have been reported yet, the criticality and ease of exploitation by authorized administrators make this a significant threat. The vulnerability was reserved in September 2025 and published in January 2026, indicating recent discovery and disclosure. Given Veeam's widespread use in enterprise backup environments, this vulnerability poses a substantial risk to organizations relying on this product for data protection and disaster recovery.

For European organizations, the impact of CVE-2025-59468 is substantial. Veeam Backup and Recovery is widely deployed across various sectors including finance, healthcare, government, and critical infrastructure within Europe. Exploitation could lead to unauthorized access to backup data, manipulation or deletion of backups, and disruption of recovery processes, potentially causing extended downtime and data loss. This could severely affect business continuity and compliance with data protection regulations such as GDPR. The ability to execute code as the postgres user also raises the risk of lateral movement within the network and further compromise of sensitive systems. Organizations with complex backup environments or those that rely heavily on automated backup and recovery workflows are particularly vulnerable. The lack of known exploits in the wild currently provides a window for proactive mitigation, but the critical severity demands urgent attention to prevent potential targeted attacks, especially in sectors with high-value data or critical operational dependencies.

1. Immediately upgrade Veeam Backup and Recovery to a patched version once available from the vendor. Monitor Veeam’s official channels for patch releases. 2. Restrict Backup Administrator privileges strictly to trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce risk of credential compromise. 3. Implement network segmentation and firewall rules to limit access to the Veeam Backup server interfaces only to authorized management networks and systems. 4. Monitor logs and audit trails for unusual password parameter usage or anomalous administrative activity that could indicate exploitation attempts. 5. Conduct regular security assessments and penetration testing focused on backup infrastructure to identify potential weaknesses. 6. Employ application-layer firewalls or intrusion detection/prevention systems (IDS/IPS) capable of detecting malicious payloads targeting the password parameter. 7. Develop and test incident response plans specifically addressing backup system compromises to ensure rapid containment and recovery. 8. Consider temporary compensating controls such as disabling remote administrative access if feasible until patches are applied.
