Authenticated path traversal / arbitrary file upload leading to RCE in Veeam Backup & Replication
CVE-2022-26500 is an authenticated vulnerability in Veeam Backup & Replication (reported affecting 9.5U3, 9.5U4, 10.x, and 11.x) caused by improper limitation of path names (path traversal). An authenticated attacker can leverage traversal to reach internal API functionality and perform an unrestricted file upload to attacker-chosen locations outside the intended directory. By uploading a server-executable payload (e.g., an ASPX webshell), the attacker can achieve remote code execution on the Veeam server.
