AI-Generated

The vulnerability allows authenticated, low-privileged backend users in TYPO3 to exploit an unsecured AJAX endpoint for inline editing, enabling them to access arbitrary database fields beyond their permissions. This can lead to the disclosure of sensitive information, including user password hashes. Organizations using TYPO3 should prioritize addressing this issue, particularly those with multiple backend users, to mitigate the risk of unauthorized data exposure.

Original NVD Description

The extension fails to restrict a backend AJAX endpoint for inline editing to fields the current user is permitted to see or edit. An authenticated, low-privileged backend user can supply arbitrary table, field and record parameters, and trigger an error response that discloses the current database value of the requested field, leading to disclosure of sensitive information such as backend and frontend user password hashes. Exploitation requires a valid, authenticated TYPO3 backend user account with access to the extensions backend module.
