CVE-2025-8426

Estado: AnalizadaCrítica (9.4)—

Marvell QConvergeConsole compressConfigFiles Directory Traversal Information Disclosure and Denial-of-Service Vulnerability. This vulnerability allows remote attackers to disclose sensitive information or to create a denial-of-service condition on affected installations of Marvell QConvergeConsole. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the implementation of the compressConfigFiles method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose sensitive information or to create a denial-of-service condition on the system. Was ZDI-CAN-24915.

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/PR:N sin interacción permite T1190. Directory traversal (CWE-22) accede a archivos sensibles (T1005) y el DoS explícito justifica T1499.004 (exhaustión de recursos).

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.
