A vulnerability allowing an authenticated domain user to perform remote code execution (RCE) on the Backup Server.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-21669) affects Veeam Backup and Replication 13.0.1 and permits an authenticated domain user to perform remote code execution on the Backup Server. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) indicates network attack vector, low complexity, required privileges of an authenticated user, no user interaction, and complete impact on confidentiality, integrity, and availability. The vulnerability is categorized under CWE-693. No patch or vendor advisory details are currently available, and the product is not a cloud service.
Potential Impact
Successful exploitation allows an authenticated domain user to execute arbitrary code remotely on the Backup Server, potentially leading to full system compromise including complete loss of confidentiality, integrity, and availability of backup data and services. This can severely disrupt backup operations and data recovery capabilities.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict authenticated user access to the Backup Server and monitor for suspicious activity. Avoid granting unnecessary domain user privileges on the Backup Server.
