🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1190 Exploit Public-Facing Applicationinitial access95 %
Impacto principalT1059 Command and Scripting Interpreterexecution90 %

Vector CVSS con AV:N/PR:N/UI:N indica explotación remota sin privilegios ni interacción (T1190). Deserialization de datos no confiables en aplicación web expuesta ejecuta código arbitrario (T1059). CWE-94 confirma ejecución de código.

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.
