T1059Command and Scripting Interpreterexecution80 % - Impacto secundario
T1499Endpoint Denial of Serviceimpact60 %
AV:N/PR:N permite explotación remota sin privilegios (T1190). Inyección SMTP (CWE-77) en endpoint /osrest/api permite ejecutar comandos arbitrarios vía SMTP (T1059) o causar DoS (T1499).
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.
