Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1210Exploitation of Remote Serviceslateral movement90 %
El vector AV:N/PR:L indica red con privilegios, luego T1210. La lectura fuera de límites no revela datos y la petición se rechaza; no hay ejecución de comandos ni DoS descritos, así que no se asigna impacto.
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.
