CVE-2026-5088

Estado: AnalizadaAlta (7.5)—

Apache::API::Password versions through 0.5.2 for Perl can generate insecure random values for salts.

The _make_salt and _make_salt_bcrypt methods will attept to load Crypt::URandom and then Bytes::Random::Secure to generate random bytes for the salt. If those modules are unavailable, it will simply return 16 bytes generated with Perl's built-in rand function.

The rand function is unsuitable for cryptographic use.

These salts are used for password hashing.

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.

Módulo Perl expuesto en red genera salts criptográficamente débiles (rand() en lugar de Crypt::URandom), permitiendo recuperación de hashes de contraseñas y ataques de fuerza bruta (CWE-338: weak RNG).

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.
