CVE-2026-36958

Estado: ModificadaAlta (7.5)—

A denial-of-service vulnerability exists in the U-SPEED N300 V1.0.0 wireless router. By sending a large number of concurrent HTTP requests to random or non-existent endpoints on the web management interface, an attacker can exhaust system resources in the embedded Boa HTTP server. This causes the router web interface to become unresponsive and may require manual reboot to restore normal operation.

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 CVSS:3.1/AV:N/AC:L/PR:N/UI:N indica red sin autenticación (T1190). CWE-400 y descripción refieren exhaustión de recursos HTTP contra servidor web expuesto, causando indisponibilidad (T1499).

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.
