SQL injection in CMS Made Simple - CVE-2019-9693

Description

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

The vulnerability exists in the "class.showtime2_data.php" file due to insufficient sanitization of user-supplied data passed via the "_updateshow" (parameter show_id), "_inputshow" (parameter show_id), "_Getshowinfo" (parameter show_id), "_Getpictureinfo" (parameter picture_id), "_AdjustNameSeq" (parameter shownumber), "_Updatepicture" (parameter picture_id), and "_Deletepicture" (parameter picture_id) functions. A remote authenticated attacker 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.
