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.
Solution:
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
