Dear Sir/Madam,

yahoo open redirect vulnerability and reported it to yahoo 10 days ago.

However, yahoo did nothing about it.

I just found one open url redirection vulnerability in yahoo.

This attacks doesn't even need users to login yahoo. My test is on all
browsers in all computer systems.

I use "poc of exploit" to denote that url redirection works.

Now I will use a website just built by me for the following tests. The
website is "http://www.tetraph.com". We can think this website is
malicious, because it is fully under my control.
