Estado: AnalizadaAlta (8.7)—

A vulnerability was found in TOTOLINK A702R, A3002R and A3002RU 3.0.0-B20230809.1615 and classified as critical. This issue affects some unknown processing of the file /boafrm/formNtp of the component HTTP POST Request Handler. The manipulation of the argument submit-url leads to buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

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 componente HTTP POST (PR:L) de router remoto sin UI requiere acceso autenticado (PR:L). Permite ejecución de código arbitrario y potencialmente escalada de privilegios en dispositivo embebido.

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.
