Today i'll share how i found content spoofing on itbit with you ..
Proof of concept:-
1) Itbit sent failed login notification to user upon every unsucessful login attempt containing the time of login attempt,user-agent and ip. so i just did an unsuccessful login and intercept the request using proxy tools (burpt or tamper data)
2) Now just change the user-agent strong and forward the request
3) now user will get the modified user-agent string in the email
