CVE-2024-28875

Estado: ModificadaAlta (8.1)—

A security flaw involving hard-coded credentials in LevelOne WBR-6012's web services allows attackers to gain unauthorized access during the first 30 seconds post-boot. Other vulnerabilities can force a reboot, circumventing the initial time restriction for exploitation.The backdoor string can be found at address 0x80100910

It is referenced by the function located at 0x800b78b0 and is used as shown in the pseudocode below:

Where 1 is the return value to admin-level access (0 being fail and 3 being user).

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.

Credenciales hardcodeadas (CWE-798) en servicio web expuesto (AV:N) permiten acceso no autorizado sin autenticación legítima. Vector de red sin privilegios indica T1190. El impacto es acceso a cuenta válida con permisos de administrador.

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.
