CVE-2025-51540

Estado: AplazadaMedia (5.3)—

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 The lack of salting and use of a fast, outdated algorithm makes it feasible to recover plaintext credentials using precomputed tables or GPU-based cracking tools.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

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
