CVE-2025-51540
EzGED3 3.5.0 stores user passwords using an insecure hashing scheme: md5(md5(password)). This hashing method is cryptographically weak and allows attackers to perform efficient offline brute-force attacks if password hashes are disclosed. The lack of salting and use of a fast, outdated algorithm makes it feasible to recover plaintext credentials using precomputed tables or GPU-based cracking tools. The vendor states that the issue is fixed in 3.5.72.27183.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N

Este método de hash es criptográficamente débil y permite a los atacantes realizar ataques de fuerza bruta sin conexión si se divulgan los hashes de las contraseñas. La ausencia de sal y el uso de un algoritmo rápido y obsoleto permiten recuperar credenciales de texto plano mediante tablas precalculadas o herramientas de descifrado basadas en GPU.
