Vulnerability Title
ChurchCRM vulnerable to a time-based blind SQL injection via the 1FieldSec parameter
Source: CVE Program / CVE List V5
Vulnerability Description
ChurchCRM is an open-source church management system. In ChurchCRM 6.2.0 and earlier, there is a time-based blind SQL injection in the handling of the 1FieldSec parameter. Injecting SLEEP() causes deterministic server-side delays, proving the value is incorporated into a SQL query without proper parameterization. The issue allows data exfiltration and modification via blind techniques.
