CVE-2026-74888

Estado: AnalizadaAlta (8.7)—

openssl_encrypt versions before 1.4.0 use a non-standard PBKDF2 key derivation construction with iterations=1 per call in an outer loop, creating a KDF whose security properties have not been formally analyzed. Attackers can exploit this weakened key derivation to more efficiently crack passwords protecting legacy encrypted files compared to standard PBKDF2 implementations.

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.

CVE de criptografía débil (CWE-327) en función openssl_encrypt: PBKDF2 con iteraciones=1 expone archivos legados a descifrado eficiente. AV:N/PR:N/UI:N → explotación remota sin privilegios; impacto es lectura de datos cifrados (T1552.007) y ataque de fuerza bruta contra contraseñas (T1110.001).

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.
