CVE-2026-71958

Estado: AplazadaCrítica (9.3)—

D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain a buffer overflow vulnerability in the quicksetup.cgi interface. A remote attacker can write overly long strings to the test4, ssid2, and username fields and execute arbitrary commands by crafting a specific payload, or cause the device to crash.

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 interfaz web accesible remotamente sin autenticación (AV:N, PR:N) permite ejecución de comandos arbitrarios o DoS. CWE-120 confirma desbordamiento de búfer.

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.
