CVE-2023-49960Network attack vector

Unauthenticated arbitrary file write via upload filename

Published Feb 26, 2024 · Updated Apr 22, 2025

Path traversal in Indu-Sol PROFINET-INspektor NT 2.4.0 and earlier allows remote attackers to write arbitrary files via upload filenames. The httpuploadd service accepts a crafted filename at /upload without confining the destination to the intended upload directory. No authentication or user interaction is required, and successful requests can overwrite files writable by the root-running service.
