vBulletin 3.6.10
Although 3.6.9 was intended to be the final maintenance release for the 3.6.x series, the discovery of a CSRF (cross-site request forgery) vulnerability in vBulletin over the weekend has forced the release of an update to plug the hole.
The CSRF problem potentially enabled an administrator who had been lured to a third-party site to unknowingly submit forms located on the forum he or she administers, resulting in potential damage to the forum. Actions performed via the Admin Control Panel are not vulnerable.
The fix for the CSRF issue involves many files and many templates, so unfortunately it is not feasible to produce a patch or a plugin to address the problem. Only a full-scale update will work.
We recommend that customers running versions of vBulletin older than 3.6.10 upgrade as soon as possible.
Template Changes Automatically Applied
With one exception (userinfraction_view), all the template changes in this release require a revert, but they are simple to apply so the upgrade script will attempt to do this for you. The list below shows which templates will be affected by the change, and how they will be altered. Customized templates will be automatically updated, but your customized changes will be retained.
A security hole involving a CSRF (cross-site request forgery) vulnerability was reported to us over the weekend, requiring changes to significant numbers of templates and files in all of our products including vBulletin 3.x, Blog and Project Tools. The CSRF problem potentially enabled an administrator who had been lured to a third-party site to unknowingly submit forms located on the forum he or she administers, resulting in potential damage to the forum. Actions performed via the Admin Control Panel are not vulnerable.
Incidentally, this vulnerability is not unique to vBulletin - many web applications are affected and always have been, due to the very nature of the web.
It was decided that rather than push ahead and release 3.7.0, it would be better to roll out a further release candidate containing the fix for this problem, as the changes are widespread and it would not be prudent to label 3.7.0 as ’stable’ before it has had at least one outing in pre-release form.
As we release vBulletin 3.7.0 Release Candidate 4, we are simultaneously releasing 3.6.10, which contains various bug fixes back-ported from 3.7.0, and of course the fix for the security problem. New versions of Blog and Project Tools will follow shortly in the coming days.
Unfortunately, due to the number of file and template changes required by the security fix, it is not practical to provide a patch or plugin to resolve the problem - only a full-scale upgrade will be sufficient.
