CVE-2026-28764

Estado: ModificadaAlta (7.8)—

A heap-based buffer overflow vulnerability exists in the LXF element parsing functionality of MediaInfoLib (version(s): 26.01). A specially crafted .lxf file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

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 + UI:R sugieren ejecución cliente (T1203): usuario abre archivo .lxf malicioso. Buffer overflow permite ejecución de código arbitrario (T1059). Acceso local permite lectura de datos (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.
