#VU21601 SQL injection in vBulletin - CVE-2019-17271

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via "where" parameter to "ajax/api/hook/getHookList" or "ajax/api/widget/getWidgetList" API endpoints. A remote authenticated attacker with "canadminproducts", "canadminstyles" (1) or "canusesitebuilder" (2) permissions can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
