Motivian Content Management System Arbitrary File Upload Vulnerability

A file upload vulnerability has been identified in Motivian Content Management System version 41.0.0. This vulnerability allows remote attackers to execute arbitrary code by uploading files with crafted extensions, such as .php, .png, or .txt, containing malicious code. The issue arises in the 'Content/Gallery/Images' component, where improper file validation enables the upload of harmful files that could be executed on the server.

Impact

Exploitation of this vulnerability could lead to unauthorized execution of arbitrary code on the server.

Reproduction

The vulnerability can be reproduced by uploading a file through the 'Content/Gallery/Images' component. The uploaded file can have various extensions, including .php, .png, or .txt. For example, a .php file containing malicious code or a .txt file with the EICAR test string can be uploaded, demonstrating the vulnerability by executing the uploaded code or triggering a response from the server's antivirus software.

Remediation

To address this vulnerability, it is recommended to implement strict file validation measures, including checking MIME types and inspecting file contents. Additionally, randomizing filenames and restricting upload directories can help mitigate the risk.
