CVE-2026-16139

Estado: AnalizadaAlta (7.2)—

In Progress ShareFile Storage Zones Controller versions <= 5.12.5 and <= 6.0.2, an authenticated zone administrator can exploit improper validation in the download preparation flow, enabling attacker-controlled files to be written outside the intended preparation directory. This can lead to remote code execution in v5 versions. Remote code execution is not confirmed on v6 versions.

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.

Administrador de zona autenticado explota validación deficiente (CWE-20, CWE-22) para escribir archivos fuera del directorio permitido, con RCE confirmado en v5 (T1059). AV:N/PR:H requiere acceso remoto con privilegios previos (T1210). Impactos: manipulación de datos (T1565.001), ejecución de código

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.
