CVE-2024-50559Network attack vector

Integrity compromise via certificate filename traversal

Published Nov 12, 2024 · Updated Nov 12, 2024

Path traversal in Siemens SCALANCE M-800 and RUGGEDCOM RM1224 firmware before 8.2 allows remote authenticated users to alter system integrity. The certificate-handling path fails to validate certificate filenames and appends attacker-controlled values outside the intended path. Exploitation requires an authenticated certificate workflow and user interaction; the published consequence is limited to system-integrity modification.
