By- Samrat Das Hi Readers Recently in one of my pentest research, I found a CMS " WonderCMS" hosted in github. Curious to explore its functionalities, I downloaded and set it up in my local system. After fiddling with the source code, I found that it did not have any kind of file upload security mechanism and allowed the user to upload any file type! After reporting it to them, I did not receive any security relevant response, hence decided to publish a blog on this. Title of the Vulnerability:   Arbitrary File Upload Vulnerability Class: Security Misconfiguration Technical Details & Description: The application source code is coded in a way which allows arbitrary file extensions to be uploaded.
