CVE-2026-54202

Estado: AplazadaAlta (8.5)—

Tobit Laboratories AG TeamDavid's Webbox is vulnerable to a path traversal vulnerability in the archive creation functionality. Because the archive path is user-controlled and insufficiently validated, an attacker can manipulate the input to traverse directories. This allows the creation of folders in arbitrary locations, including sensitive directories such as C:\Windows or for different users. This issue affects TeamDavid before Rollout 528.

Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.

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.

Acceso remoto con privilegios (PR:L) permite manipular rutas en funcionalidad de archivos para crear carpetas en directorios sensibles (Windows, otros usuarios), causando manipulación del sistema de archivos e potencial acceso a datos.

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.
