CVE-2025-7214
FNKvision FNK-GU2 MD5 shadow risky encryption
Description
A vulnerability classified as problematic was found in FNKvision FNK-GU2 up to 40.1.7. Affected by this vulnerability is an unknown functionality of the file /etc/shadow of the component MD5. The manipulation leads to risky cryptographic algorithm. It is possible to launch the attack on the physical device. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.
