CVE-2026-22081

Estado: AplazadaAlta (8.8)—

This vulnerability exists in Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) due to the missing HTTPOnly flag for session cookies associated with the web-based administrative interface. A remote at-tacker could exploit this vulnerability by capturing session cookies transmitted over an insecure HTTP connection.

Successful exploitation of this vulnerability could allow the attacker to obtain sensitive information and gain unau-thorized access to the targeted device.

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.

Vector AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). Captura de cookies de sesión sin HTTPOnly en HTTP proporciona credenciales de acceso administrativo no autorizado.

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.
