Technical details

A path traversal vulnerability (CWE-22) exists in the Blocks module of Daylight Studio FuelCMS v1.5.2. The vulnerability is located within the 'fuel/modules/fuel/controllers/Blocks.php' component, where insufficient validation of user-supplied input allows for directory traversal sequences. An attacker with low-privileged (PR:L) network access can exploit this flaw to bypass directory restrictions and read arbitrary files on the underlying file system. This can result in the disclosure of sensitive information such as configuration files or system credentials. While a proof-of-concept exists, no official patch is explicitly detailed in the advisory, though users are encouraged to monitor the official GitHub repository for updates.
