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.
