Veeam Backup & Replication Remote Code Execution Vulnerability

Added to KEV: 2022-12-13Federal patch deadline: 2023-01-03⚠ USED IN RANSOMWARE CAMPAIGNS

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

The Veeam Distribution Service in Backup & Replication allows unauthenticated users to access internal API functions, potentially leading to remote code execution. The high EPSS score and confirmed exploitation by CISA indicate a significant and urgent risk. This flaw is rated as HIGH severity.

This vulnerability is actively being exploited in the wild. It is remotely exploitable by unauthenticated users accessing internal API functions.

Recommended Action

Organizations using Veeam Backup & Replication should apply available patches to address this vulnerability. Implement network segmentation and restrict access to internal API functions to authorized users only.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2022-26500 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2022-26500 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
