How the Exploit Works
The vulnerability lies in the ‘catch_dark_mode’ shortcode of the Catch Dark Mode plugin. Attackers with at least Contributor-level access can exploit this vulnerability by including arbitrary .php files via the shortcode. Since the shortcode does not properly sanitize or validate the included files, this allows the execution of any PHP code in those files. Consequently, attackers can bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included.
Conceptual Example Code
The following pseudocode exemplifies how an attacker might exploit this vulnerability:
catch_dark_mode('[include] /path/to/malicious.php [/include]');In this example, ‘malicious.php’ is an arbitrary PHP file that the attacker has uploaded to the server. When the Catch Dark Mode plugin processes the shortcode, it includes and executes the code in ‘malicious.php’, leading to potential system compromise or data leakage.
