CVE-2025-27397
Siemens SCALANCE File Log Path Traversal Vulnerability
Description
A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly limit user controlled paths to which logs are written and from where they are read. This could allow an authenticated highly-privileged remote attacker to read and write arbitrary files in the filesystem, if and only if the malicious path ends with 'log' .
