CVE-2026-7786

Estado: AplazadaCrítica (9.8)—

Jinan USR IOT Technology Limited (PUSR) USR-W610 RS232/485 to Wi-Fi/Ethernet Converter device firmware contains plaintext administrative credentials embedded in the firmware image. These credentials can be extracted through firmware analysis and used to authenticate to device services.

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.

AV:N/AC:L/PR:N indica exposición de red sin privilegios previos (T1190). Las credenciales administrativas en claro del firmware permiten autenticación con privilegios (T1078.001) y potencial escalada local (T1068).

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.
