CVE-2016-20040

Estado: AplazadaAlta (8.6)—

TiEmu 3.03-nogdb+dfsg-3 contains a buffer overflow vulnerability in the ROM parameter handling that allows local attackers to crash the application or execute arbitrary code. Attackers can supply an oversized ROM parameter to the tiemu command-line interface to overflow the stack buffer and overwrite the instruction pointer with malicious addresses.

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:L sin UI:R indica acceso local sin interacción (T1068). Buffer overflow en parámetro ROM permite ejecución de código arbitrario (T1059) y potencialmente acceso a datos en memoria (T1005).

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.
