CVE-2012-1502

Estado: ModificadaAlta (7.5)—💥 Exploit

Double free vulnerability in the PyPAM_conv in PAMmodule.c in PyPam 0.5.0 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a NULL byte in a password string.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
