CVE-2023-42791Public exploitNetwork attack vector

Authenticated code execution via traversal file upload

Published Feb 20, 2024 · Updated Aug 2, 2024

Relative path traversal in Fortinet FortiManager and FortiAnalyzer allows remote authenticated users to execute arbitrary code via HTTP. The authenticated upload endpoint accepts parent-directory sequences in its filename field and writes supplied content outside the intended upload directory. Low-privileged GUI access is required; overwriting the dynamic-loader preload file can trigger root-level shell execution on logout.
