A time-based blind SQL Injection vulnerability exists in the ChurchCRM 5.13.0 and prior EditEventAttendees.php within the EN_tyid parameter. The parameter is directly inserted into an SQL query without proper sanitization, allowing attackers to inject malicious SQL commands. Please note that the vulnerability requires Administrator permissions. This flaw can potentially allow attackers to delay the response, indicating the presence of an SQL injection vulnerability. While it is a time-based blind injection, it can be exploited to gain insights into the underlying database, and with further exploitation, sensitive data could be retrieved.
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.
