CVE-2026-2017

Estado: AnalizadaAlta (8.9)—

A vulnerability was detected in IP-COM W30AP up to 1.0.0.11(1340). Affected by this issue is the function R7WebsSecurityHandler of the file /goform/wx3auth of the component POST Request Handler. The manipulation of the argument data results in stack-based buffer overflow. The attack may be performed from remote. The exploit is now 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 endpoint remoto sin autenticación (AV:N/PR:N/UI:N). Permite ejecución de código arbitrario (VC:H/VI:H/VA:H) y potencial escalada de privilegios en firmware.

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.
