Detailsinfo

A vulnerability classified as critical was found in EzGED3 3.5.0. This vulnerability affects an unknown function of the component Web Interface. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

EzGED3 3.5.0 contains an unauthenticated arbitrary file read vulnerability due to improper access control and insufficient input validation in a script exposed via the web interface. A remote attacker can supply a crafted path parameter to a PHP script to read arbitrary files from the filesystem. The script lacks both authentication checks and secure path handling, allowing directory traversal attacks (e.g., ../../../) to access sensitive files such as configuration files, database dumps, source code, and password reset tokens. If phpMyAdmin is exposed, extracted credentials can be used for direct administrative access. In environments without such tools, attacker-controlled file reads still allow full database extraction by targeting raw MySQL data files. The vendor states that the issue is fixed in 3.5.72.27183.

The advisory is shared for download at ballpoint.fr. This vulnerability was named CVE-2025-51539 since 06/16/2025. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading to version 3.5.72.27183 eliminates this vulnerability.
