🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1005Data from Local Systemcollection75 %
UI:R (interacción del usuario requerida) en contexto web → T1203. CSRF permite al atacante enviar mensajes masivos como el usuario legítimo, accediendo a datos de no respondientes (T1005). CWE-22 sugiere manipulación de parámetros.
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.
