  to perform a SQL injection and access sensitive database information.

  - CVE-2020-23150: A SQL injection vulnerability in config.inc.php allows attackers to access
  sensitive database information via a crafted GET request to 'install/lib/ajaxHandlers/ajaxDbInstall.php'.

  - CVE-2020-23151: The application allows command injection by sending a crafted GET request to
