Basic info — Open Redirect
Open Redirect (also known as Unvalidated Redirects and Forwards) occurs when a web application accepts user-supplied input and redirects the user to an arbitrary URL without proper validation.

How to find entry points to test?
Burp Proxy history & Burp Sitemap (look at URLs with parameters)
Google dorking. E.g: inurl:redirectUrl=http site:target.com

Look for hidden redirect parameters, for e.g.:
/redirect?url={payload}&next={payload}&redirect={payload}&redir={payload}&rurl={payload}&redirect_uri={payload}

/?url={payload}&next={payload}&redirect={payload}&redir={payload}&rurl={payload}&redirect_uri={payload}
