Estado: AnalizadaAlta (7)—

An Improper link resolution before file access ('link following') vulnerability in the File Shredder module as used in Bitdefender Total Security and Internet Security on Windows allows a less-privileged local user to elevate rights by leveraging a race conditions via Symbolic Links.

This issue affects Total Security: before 27.0.58.315; Internet Security: before 27.0.58.315.

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.

UI:R + AV:L indican interacción del usuario (abrir archivo preparado). La vulnerabilidad de race condition en symlinks requiere que el usuario ejecute la acción de shredding, activando la ejecución maliciosa. El impacto es escalada de privilegios (PR:L → VC:H).

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.
