CVE-2011-10025

Estado: AplazadaAlta (8.5)—

Subtitle Processor 7.7.1 contains a buffer overflow vulnerability in its .m3u file parser. When a crafted playlist file is opened, the application converts input to Unicode and copies it to a fixed-size stack buffer without proper bounds checking. This allows an attacker to overwrite the Structured Exception Handler (SEH) and execute arbitrary code.

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 parser de .m3u al abrir un archivo preparado (UI:R, AV:L). Sobrescritura de SEH permite ejecución de código arbitrario.

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.
