CVE-2026-104806

Estado: AplazadaMedia (5.5)—

DigitalCanion has discovered a path traversal vulnerability that allows an attacker to access files outside of the intended directory.

The specific flaw exists within the Maintenance → System Logs functionality of the web management portal listening on TCP port 443. The application fails to properly validate user-supplied file paths, allowing an attacker to manipulate the requested path and traverse the underlying directory structure.

By exploiting this vulnerability, an attacker can access and download files located outside the intended system logs directory, including potentially sensitive system and application files.

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.

Vector CVSS indica acceso remoto con PR:H (requiere privilegios altos). Path traversal permite lectura no autorizada de archivos del sistema. T1210 por servicio remoto con autenticación; T1005 y T1552 por acceso a datos y potenciales secretos del sistema.

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.
