[CONFSERVER-94604] Path Traversal in Confluence Data Center
Updated the ticket with Mitigation options
- This fix was included in the Confluence Cloud Migration Assistant plugin (which we sometimes refer to as CCMA), and version 3.9.5 (or later) contains the fix. So for a mitigation step, all you need to do is login to Confluence as an admin, select General Configuration >> Manage Apps and then locate and upgrade the CCMA plugin to 3.9.5 or later. Confluence upgrade is not required in this case.
- The other option is you can deactivate the CCMA plugin altogether if don't plan for the upgrade.
as Stephan asked, is it enough to desactivate this module (CCMA) because we dont use it as there are no plan to go on cloud.
Thanks
Michael
Wait, do we have to Upgrade Confluence or do we (also) need to upgrade the Plugin?
Thank you, @ankita for that information. Please endeavor to include important relevant information like that in future disclosures, especially if it's for a plugin that might not have been automatically upgraded with the system.
Would it also be valid to just deactivate this plugin? Or would this introduce other side effects?

Can we get a little more information than "undefinable vulnerability"? For those of us unable to upgrade immediately due to some unaddressed bugs introduced in the point releases for this LTS, knowing an attack surface or mitigation for this vulnerability is vital.
I have a server instance and have just tried to upgrade exactly as per the recommendations, only to be told that my (and I assume every other server users) expired license does not allow the upgrade. If it is not possible for Server Users to upgrade at all would you please remove that section entirely and replace it with some useful recommendations.
