🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1190Exploit Public-Facing Applicationinitial access90 % - Impacto principal
T1499.004Application or System Exploitationimpact85 %
AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). CWE-770 y descripción de rate-limiting sugieren DoS por agotamiento de recursos (T1499.004).
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.
