How the Exploit Works
The vulnerability exploits a flaw in the /index.php/plus endpoint of FoxCMS 1.2.6. A reflected Cross Site Scripting (XSS) attack occurs when an attacker injects a malicious script into a URL, which is then executed by the victim’s browser when they visit the manipulated site. This malicious script can steal users’ session cookies, deface web sites, or redirect the user to malicious sites.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited. The attacker crafts a malicious URL containing a script that gets executed when the URL is accessed.
GET /index.php/plus?input=<script>malicious_code</script> HTTP/1.1
Host: vulnerable-website.comWhen a user clicks on this URL, the malicious script embedded in the URL is executed in the user’s browser. This could lead to a variety of malicious outcomes, such as session hijacking, data theft, or system compromise.
Recommendation for Mitigation
The most effective solution to mitigate this vulnerability is to apply the patch provided by the vendor. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary protection by blocking known malicious patterns. Regular updates and patches are crucial to maintaining system security and integrity. Users are always encouraged to stay informed about the latest cybersecurity threats and to take proactive steps to protect their systems and data.
