Technical details
An information disclosure vulnerability exists in Xerte Online Toolkits versions 3.15 and earlier due to the exposure of sensitive system information in the setup component. Specifically, the 'software_installed.php' file within the /setup directory renders the '$xot_setup->root_path' variable directly into the HTML response. An unauthenticated remote attacker can trigger this by sending a GET request to the /setup page. The resulting disclosure of the absolute filesystem path can be leveraged to facilitate more complex attacks, such as providing the necessary path information for relative path traversal exploits in 'connector.php'. A patch has been committed to the project's repository to remove the path disclosure.
