CVE-2024-31151

Estado: ModificadaCrítica (9.8)—

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 password string can be found at addresses 0x 803cdd0f and 0x803da3e6:

It is referenced by the function at 0x800b78b0 and simplified in the pseudocode below:

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

While there's no legitimate functionality to change this password, once authenticated it is possible manually make a change by taking advantage of TALOS-2024-XXXXX using HTTP POST paramater "Pu" (new user password) in place of "Pa" (new admin password).

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 remoto accesible sin autenticación previa (AV:N/AC:L/PR:N/UI:N). Acceso inicial a cuenta válida y posible escalada administrativa.

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.
