CVE-2024-29858Network attack vector

Arbitrary file processing via spoofed upload path

Published Mar 21, 2024 · Updated Aug 5, 2024

Improper upload validation in MISP before 2.4.187 allows remote attackers to make the server inspect an attacker-supplied temporary path. The __uploadLogo method passes the client-controlled tmp_name value to mime_content_type before validating and constraining the path. The request is network-reachable without authentication; public sources do not establish whether file inspection exposes contents or yields code execution.
