Estado: AplazadaBaja (2.1)—

A weakness has been identified in Chengdu Feiyuxing Technology Feiyu Star Router B-MB5E202-210322-r11656. Affected is an unknown function of the file /send_order.cgi?parameter=loginout of the component Cookie Handler. This manipulation of the argument session_id causes command injection. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

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

AV:N+PR:L indica explotación de servicio remoto con autenticación (T1210). CWE-74/77 y 'command injection' en /send_order.cgi confirman ejecución de comandos (T1059). Manipulación de cookie_session_id sugiere posible alteración de datos (T1565.001).

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.
