DescriptionGitHub Advisory

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.

Analysis

Technical ContextAI

SQL injection occurs when user-supplied input is incorporated into SQL queries without proper sanitization or parameterized queries.

RemediationAI

A vendor patch is available — apply it immediately. Use parameterized queries or prepared statements. Apply input validation and escape special characters. Implement least-privilege database accounts.
