CVE-2025-50644

Estado: ModificadaAlta (7.5)—

A buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 due to improper validation of user input in the qj.asp endpoint.

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 web sin autenticación (AV:N, PR:N, UI:N) explotable remotamente. Impacto DoS confirmado por A:H en CVSS; CWE-120 típicamente causa degradación de servicio.

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.
