CVE-2018-25251

Estado: AplazadaAlta (8.6)—

Snes9K 0.0.9z contains a buffer overflow vulnerability in the Netplay Socket Port Number field that allows local attackers to trigger a structured exception handler (SEH) overwrite. Attackers can craft a malicious payload and paste it into the Socket Port Number field via the Netplay Options menu to achieve code execution through SEH chain exploitation.

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.

Buffer overflow en campo local (AV:L, PR:N, UI:N) permite sobrescribir SEH y ejecutar código. Acceso local sin privilegios previos = T1068; ejecución de código mediante cadena SEH = T1059.

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.
