A vulnerability was found in UTT HiPER 840G up to 3.1.1-190328. It has been declared as critical. This vulnerability affects the function sub_416928 of the file /goform/formConfigDnsFilterGlobal of the component API. The manipulation of the argument GroupName leads to buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. 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 en API remota requiere PR:L (acceso autenticado a red adyacente), derivando a T1210. Impacto en ejecución de código remoto (CWE-119/120 típicamente permite RCE).

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.
