Invision Power Board 2.1.6 is a security release.
It is not clear if this patch will solve the spam problems we've been having. Please let me know if you encounter any spam posts... They look like they're filled with garbage characters. Thanks to those Apples who have been letting me know when they spot 'em.
EDIT: Based on what I'm reading on the Invision boards, it looks like this version (2.1.6) is not vulnerable to these attacks. In fact, one of the members of that board said that since installing 2.1.6 he hasn't seen any of the "justxpl" messages. I am hopeful that the problem disappears here too.
ANOTHER EDIT: I did a more thorough security sweep and found that malicious files had, in fact, been uploaded to the site on May 15, 2006 (beware the ides of May?). I am currently investigating if these files were activated or not -- it does not appear that they were, so the bomb was in place but did not detonate. I am removing the malicious files from the server.
A THIRD EDIT: I've enabled an advanced security system at the front-end of the forum. When a new user is registering for the Orchard, they must type in a randomly-generated code to complete their registration. This is to defeat automated registration programs that are likely being used by these spammers.
I applied this patch this afternoon. The Orchard was unavailable for about 15 minutes to allow for the patch. Please let me know if you spot anything that doesn't work after this upgrade.
