CVE-2025-53783

Estado: AnalizadaAlta (7.5)—

Heap-based buffer overflow in Microsoft Teams allows an unauthorized attacker to execute code over a network.

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 Teams con UI:R (interacción del usuario) y AV:N → ejecución de código en cliente (T1203). Desbordamiento de heap permite ejecución de comandos arbitrarios (T1059).

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.
