This issue affects pbkdf2: from 3.0.10 through 3.1.2.

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/AC:L permite explotación remota sin privilegios (T1190). VI:H/SI:H sugieren manipulación de integridad; CWE-20 de validación deficiente en pbkdf2 permite falsificación de firmas (T1565.002). SI:H también apunta a manipulación de sesiones/identidades (T1556).

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.
