Description

ChurchCRM the setup page. The DB_PASSWORD field in the installation form is written
directly into Include/Config.php without sanitization, allowing PHP code
injection. The injected config file is then included on every request,
triggering the payload. Note that the fix claimed in 5.21.0 only added
a strlen check on the password field, leaving the injection intact.
