XF 1.4 External Redirect / Porn Spamming?

#1
Hello.

We've noticed that we are getting loads (and I mean loads!) of backlinks from porn sites recently and they seem to be using our External Redirect proxy to do it. I don't know why or how....here is an example:

https://www.gravyforthebrain.com/xenforo/proxy.php?link=http://2beeg.mobi

This happens even if users are not logged in. Is there any way I can stop this external redirect from working/happening, and has anyone else seen anything like this? We've done a malware search but come up with nothing, and in the above example, '2beeg' doesn't appear anywhere in our db.....

Would really appreciate some advice on this one!

Thanks!

Hugh.

Since you've tagged this as 1.4, I don't recall when we changed the approach of the link proxy, but I think it may have been after this version. In newer versions, it doesn't try to interject any URLs in the middle when a link is clicked, so there's never any reason to have the link redirection page displayed. (In 1.4, there may be some edge cases that could trigger it.)

However, if you want, you can empty the link_redirect template contents which will prevent any URL like that from working.

Hi Mike,

Thanks for the reply. I guess that spawns two further questions from me! Firstly, if I upgrade the installation to V2 will it solve this problem, and secondly, how do I empty the link_redirect template?

By newer versions, I was referring to 1.5 specifically -- 2.0 is still in beta so we don't recommend running it in production. (It's also a much bigger update.)

You can go into the templates section of the control panel, search for "link_redirect" and empty the contents of the template.
