Estado: AplazadaAlta (8.7)—

A flaw has been found in Shenzhen Libituo Technology LBT-T300-HW1 up to 1.2.8. This issue affects the function start_single_service of the component Web Management Interface. Executing a manipulation of the argument vpn_pptp_server/vpn_l2tp_server can lead to buffer overflow. The attack can be executed remotely. 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.

Buffer overflow remoto (CWE-119/120) en interfaz web con PR:L sugiere explotación de servicio remoto con privilegios. AV:N y VC:H/VI:H/VA:H indican 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.
