CVE-2026-47372

Estado: AplazadaCrítica (9.1)—

Crypt::SaltedHash versions through 0.09 for Perl generate insecure random values for salts.

These versions use the built-in rand function, which is predictable and unsuitable for cryptography.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N permite explotación remota sin privilegios (T1190). Generación insegura de salts criptográficos facilita ataques de diccionario para comprometer credenciales (T1078) y acceso a almacenes de contraseñas (T1555).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
