Detailsinfo

A vulnerability classified as very critical was found in WAGO 0751-9x01, 0750-811x-xxxx-xxxx, 0750-821x-xxx-xxx, 0762-420x-8000-000x, 0762-430x-8000-000x, 0762-520x-8000-000x, 0762-530x-8000-000x, 0762-620x-8000-000x, 0762-630x-8000-000x, 0752-8303-8000-0002 and 0762-340x. This vulnerability affects some unknown processing of the component BACnet File Object. 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:

The object name of a dynamically created BACnet File Object is interpreted as a file path without sufficient validation. Because relative paths are not limited to the intended directory, an unauthenticated remote attacker can traverse outside of it and read or overwrite arbitrary files on the device, which may lead to full system compromise.

The advisory is shared for download at certvde.com. This vulnerability was named CVE-2025-41753 since 04/16/2025. 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 current price for an exploit might be approx. USD $0-$5k (estimation calculated on 10/01/2026). The MITRE ATT&CK project declares the attack technique as T1006.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
