Overview of this book

Bug bounty programs are the deals offered by prominent companies where-in any white-hat hacker can find bugs in the applications and they will have a recognition for the same. The number of prominent organizations having this program has increased gradually leading to a lot of opportunity for Ethical Hackers.

Executing code


In my opinion, the most dangerous kind of open redirect vulnerability is when it is possible to inject code into the variable that controls the redirections. For example, look at this case:

https://example.com/index.php?go=javascript:alert(document.domain)

 

Here, the go variable is using a JavaScript function to get the domain to redirect to the user. So, if a malicious user can manipulate this parameter, it is possible to redirect to other places, or it is possible to combine this vulnerability with a cross-site scripting (XSS) attack and create phishing campaigns.
