🎯 Técnicas ATT&CK

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

ExplotaciónT1210 Exploitation of Remote Serviceslateral movement85 %
Impacto principalT1059 Command and Scripting Interpreterexecution80 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation70 %

Stack-based buffer overflow en función remota (AV:N, PR:L) permite ejecución de código. El acceso requiere autenticación previa (PR:L), típico de T1210. El desbordamiento posibilita ejecutar comandos arbitrarios (T1059) y potencialmente escalar privilegios en el dispositivo (T1068).

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.
