CVE-2010-20042

Estado: AplazadaAlta (8.4)—

Xion Audio Player versions 1.0.126 and prior are vulnerable to a Unicode-based stack buffer overflow triggered by opening a specially crafted .m3u playlist file. The file contains an overly long string that overwrites the Structured Exception Handler (SEH) chain, allowing an attacker to hijack execution flow and run 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.

Vector AV:L+UI:A indica cliente local con interacción del usuario (abrir archivo .m3u preparado). SEH hijacking 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.
