How the Exploit Works
The vulnerability exists due to insufficient data sanitization in the password parameter of the mingSoft MCMS software. An attacker can craft a malicious script and send it to the password parameter, which the software processes without proper validation. This allows the attacker to extract sensitive information, which could be utilized for further exploits or harm.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. The attacker sends a HTTP POST request containing a malicious payload to the target host.
POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin&password=<script>malicious_script_here</script>Recommended Mitigation
The recommended mitigation for this vulnerability is to apply the vendor’s patch. If the patch is not available, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation can help prevent the exploit. Furthermore, regular software updates and strong, unique passwords for all accounts can also reduce the risk of this and similar vulnerabilities.
