CVE-2023-39026Public exploitNetwork attack vector

Sensitive file disclosure via encoded path traversal

Published Aug 22, 2023 · Updated Oct 3, 2024

Path traversal in FileMage Gateway 1.10.8 and earlier on Windows allows remote attackers to read sensitive host files via HTTPS. The unauthenticated /mgmnt/ handler accepts URL-encoded backslash traversal sequences and resolves them outside its intended directory. Only Windows Azure Marketplace deployments were demonstrated; testing reported non-Azure deployments as not vulnerable, and the read access exposes configuration files and SSH keys.
