CVE-2026-21670: Vulnerability in Veeam Backup and Replication
A vulnerability allowing a low-privileged user to extract saved SSH credentials.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-21670) in Veeam Backup and Replication 13.0.1 enables a low-privileged attacker to extract saved SSH credentials due to improper protection of sensitive data (CWE-522). The CVSS 3.1 base score is 7.7, reflecting network attack vector, low attack complexity, and privileges required but no user interaction. The vulnerability compromises confidentiality with a scope change, but integrity and availability remain unaffected.
Potential Impact
An attacker with low privileges can obtain SSH credentials stored by the product, potentially allowing unauthorized access to systems where those credentials are used. This exposure compromises confidentiality but does not directly impact data integrity or system availability. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — no official patch or vendor advisory is provided. Users should monitor Veeam's official channels for updates and apply any forthcoming patches promptly. Until a fix is available, restrict low-privileged user access to the Veeam Backup and Replication environment to minimize risk.
