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 movement85 % - Impacto principal
T1499Endpoint Denial of Serviceimpact80 %
El vector AV:N/PR:L indica red con privilegios (T1210). El texto describe una denegación de servicio limitada y lectura fuera de límites, sin ejecución de comandos, así que T1059 no se sustenta.
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.
