CVE-2014-3931

Estado: AnalizadaCrítica (9.8)⚠ Explotación activa

Fastping.c en MRLG (también conocido como Multi-Router Looking Glass) en versiones anteriores a 5.5.0 permite a atacantes remotos provocar una escritura de memoria arbitraria y corrupción de memoria.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Vector AV:N/PR:N/UI:N sin autenticación permite explotación remota de aplicación web (T1190). Buffer overflow (CWE-119) en fastping.c causa escritura arbitraria de memoria, permitiendo ejecución de código (T1059) y potencial DoS (T1499.004). Confirmado por KEV con explotación activa.

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.
