CVE-2025-59470 is a critical vulnerability identified in Veeam Backup and Recovery version 13.0.0 that enables remote code execution (RCE) by a user with Backup Operator privileges. The flaw arises from improper sanitization of the 'interval' or 'order' parameters, which are susceptible to command injection (classified under CWE-77). An attacker with Backup Operator rights can craft malicious input to execute arbitrary commands as the postgres user, a privileged database user within the backup system. This vulnerability does not require user interaction but does require the attacker to have Backup Operator level access, which is typically granted to trusted personnel or automated backup processes. The CVSS v3.1 score of 9.0 reflects the vulnerability's critical nature, with network attack vector (AV:N), low attack complexity (AC:L), and high privileges required (PR:H). The scope is changed (S:C), indicating that exploitation can affect resources beyond the initially vulnerable component. The impact on confidentiality and integrity is high, as attackers can manipulate backup data or exfiltrate sensitive information. Availability impact is low but still present. Although no exploits have been reported in the wild yet, the vulnerability poses a significant risk to organizations relying on Veeam Backup and Recovery for data protection. The lack of an official patch at the time of publication necessitates immediate mitigation efforts. Given the strategic importance of backup systems, exploitation could lead to severe operational disruption and data compromise.

For European organizations, this vulnerability poses a substantial risk to the integrity and confidentiality of critical backup data. Successful exploitation could allow attackers to execute arbitrary code within the backup environment, potentially leading to unauthorized data access, manipulation, or deletion. This could undermine disaster recovery capabilities and lead to prolonged downtime or data loss. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, face heightened regulatory and reputational risks. The criticality of backup infrastructure means that compromise could cascade into broader IT environment impacts. Additionally, the requirement for Backup Operator privileges means insider threats or compromised administrative accounts could be leveraged. The absence of known exploits currently provides a window for proactive defense, but the high severity demands urgent attention to prevent future attacks.

1. Immediately audit and restrict Backup Operator privileges to the minimum necessary personnel and processes. 2. Implement strict access controls and monitoring on backup systems to detect anomalous commands or parameter usage related to 'interval' or 'order'. 3. Employ network segmentation to isolate backup infrastructure from general user networks, limiting exposure. 4. Use application whitelisting and endpoint detection to identify suspicious activities involving the postgres user or backup processes. 5. Regularly review and update credentials associated with backup operators to prevent unauthorized access. 6. Monitor vendor communications closely for official patches or updates addressing this vulnerability and apply them promptly upon release. 7. Consider temporary compensating controls such as disabling vulnerable features or restricting input parameters if feasible until patches are available. 8. Conduct security awareness training for administrators emphasizing the risks of privilege misuse and command injection attacks.
