FKIE_CVE-2020-5846

Vulnerability from fkie_nvd - Published: 2020-01-06 21:15 - Updated: 2024-11-21 05:34
Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
An insecure file upload and code execution issue was discovered in Ahsay Cloud Backup Suite 8.3.0.30 via a "PUT /obs/obm7/file/upload" request with the base64-encoded pathname in the X-RSW-custom-encode-path HTTP header, and the content in the HTTP request body. It is possible to upload a file into any directory of the server. One can insert a JSP shell into the web server's directory and execute it. This leads to full system access as the configured user (e.g., Administrator) when starting from any authenticated session (e.g., a trial account). This is fixed in the 83/830122/cbs-*-hotfix-task26000 builds.

Es posible cargar un archivo en cualquier directorio del servidor. Puede ser insertado un shell JSP en el directorio del servidor web y ejecutarlo. Esto conlleva a un acceso completo al sistema como usuario configurado (por ejemplo, Administrador) cuando es iniciado desde cualquier sesi\u00f3n autenticada (por ejemplo, una cuenta de prueba). Esto es corregido en las compilaciones 83/830122 / cbs-*-hotfix-task26000."
