CVE-2026-3729

Estado: AnalizadaAlta (7.4)—

A vulnerability was identified in Tenda F453 1.0.0.3/3.As. Impacted is the function fromPptpUserAdd of the file /goform/PPTPDClient. Such manipulation of the argument username/opttype leads to stack-based buffer overflow. The attack can be executed remotely. The exploit is publicly available and might 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.

Stack buffer overflow remoto en firmware Tenda requiere autenticación (PR:L), explotable vía servicio remoto PPTP. El overflow permite ejecución de código arbitrario (VC:H/VI:H).

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.
