To date, over  70 million domains  have been launched on servers using cPanel's software suite.

The latest version of  cPanel & WHM is 11.34, which is  v ulnerable  to multiple cross site scripting. During my bug hunting process, today I ( Christy Philip Mathew )  discovered some serious XSS v ulnerabilities in  official cPanel, WHM. It also impact on the  latest version of software. This week, Rafay Baloch (Pakistani white hat hacker) also discovered another reflective cross site scripting vulnerability in  cPanel at manage.html . The interesting part would be the whole demonstration I done with the Official cPanel Demo located at location, can be accessed via demo user & password provided by cPanel website itself i.e. These  vulnerabilities actually affect the logged in users. Proof of Concept and screenshots are as shown below:
