CVE-2026-2753

Estado: AnalizadaAlta (7.5)—

An Absolute Path Traversal vulnerability exists in Navtor NavBox. The application exposes an HTTP service that fails to properly sanitize user-supplied path input. Unauthenticated remote attackers can exploit this issue by submitting requests containing absolute filesystem paths. Successful exploitation allows the attacker to retrieve arbitrary files from the underlying filesystem, limited only by the privileges of the service process. This can lead to the exposure of sensitive configuration files and system information.

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 AV:N/AC:L/PR:N/UI:N indica explotación remota sin autenticación (T1190). La traversal de rutas permite lectura arbitraria de archivos del filesystem (T1005), sustentado en 'retrieve arbitrary files' del CWE-36.

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.
