CVE-2025-7564

Estado: AnalizadaAlta (7.1)—

A vulnerability, which was classified as critical, has been found in LB-LINK BL-AC3600 1.0.22. Affected by this issue is some unknown functionality of the file /etc/shadow. The manipulation with the input root:blinkadmin leads to hard-coded credentials. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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:L con PR:L sin UI:R indica escalada de privilegios local. El texto menciona credenciales hardcodeadas (root:blinkadmin) en /etc/shadow, permitiendo obtener acceso con privilegios elevados y lectura de credenciales almacenadas.

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.
