CVE-2025-1133

SQL Injection in ChurchCRM EID Parameter via EditEventAttendees.php

Gridware

Description

A vulnerability exists in ChurchCRM 5.13.0 and prior that allows an attacker to execute arbitrary SQL queries by exploiting a boolean-based blind SQL Injection vulnerability in the EditEventAttendees functionality. The EID parameter is directly concatenated into an SQL query without proper sanitization, making it susceptible to SQL injection attacks. An attacker can manipulate the query, potentially leading to data exfiltration, modification, or deletion.  Please note that this vulnerability requires Administrator privileges.

Weakness

Affected products

What to do

Solution: To prevent SQL injection, use prepared statements with parameterised queries. Additionally, implement input validation to reject dangerous characters, apply the principle of least privilege to database users to minimise potential damage, and assign appropriate data types in PHP, such as converting EID to an integer if it represents a numeric value.
