In GLPI before version 9.5.2, the install/install.php endpoint insecurely stores user input into the database as url_base and url_base_api. These settings are referenced throughout the application and allow for vulnerabilities like Cross-Site Scripting and Insecure Redirection Since authentication is not required to perform these changes,anyone could point these fields at malicious websites or form input in a way to trigger XSS. Leveraging JavaScript it’s possible to steal cookies, perform actions as the user, etc. The issue is patched in version 9.5.2.
