CVE-2026-4182

Estado: AnalizadaAlta (8.9)—

A weakness has been identified in D-Link DIR-816 1.10CNB05. This impacts an unknown function of the file /goform/form2Wl5RepeaterStep2.cgi of the component goahead. This manipulation of the argument key1/key2/key3/key4/pskValue causes stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. This vulnerability only affects products that are no longer supported by the maintainer.

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.

Desbordamiento de búfer en servicio web remoto (goahead) sin autenticación (PR:N, UI:N) permite ejecución de código remoto. Vector AV:N/AC:L/PR:N/UI:N = red sin privilegios = T1190. El impacto es T1059 por ejecución de código en el dispositivo.

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.
