3. Vulnerability Description  
============================  
During the security analysis, ThunderScan discovered SQL injection  
vulnerabilities in Dbox 3D Slider Lite WordPress plugin.  
  
The easiest way to reproduce the vulnerabilities is to modify the POST  
request for the slider rename or reorder and append parts of the SQL  
query to the current_slider_id parameter, the result being something  
like "current_slider_id=1 AND SLEEP(5)". Users that do not have full  
administrative privileges could abuse the database access the  
vulnerabilities provide to either escalate their privileges or obtain  
and modify database contents they were not supposed to be able to.  
  
Due to the missing nonce token, the vulnerable code is also directly  
exposed to attack vectors such as Cross Site request forgery (CSRF).
