CVE-2024-20767Known exploitationPublic exploitNetwork attack vector

Arbitrary file read via logging path traversal

Published Mar 18, 2024 · Updated Oct 21, 2025

Path traversal in Adobe ColdFusion 2023 Update 6 and earlier and 2021 Update 12 and earlier allows remote attackers to read arbitrary files. The exposed getHeartBeat method returns a UUID that the /pms logging module accepts while its file_name parameter resolves traversal sequences outside the intended log path. The Administrator interface must be internet-exposed; no authentication or user interaction is required, and disclosed exploitation reads host files.
