Cross-site request forgery (CSRF) vulnerability in Mantis 1.1.1 allows remote
attackers to create new administrative users via user_create.
Backporting the patch to 1.1.1 seems rather involved. So I'd suggest waiting for 1.2.0 here.
There were a rumors about upcoming 1.1.2, so I'd wait too but for that version. I'm sure 1.2.0 is too unstable to mark it stable...
The fixes introduced in 1.1.2 are not enough.
Please note that new vulnerabilities have been discovered, see: http://www.ush.it/team/ush/hack-mantis111/adv.txt
Thank you for the link, I'll check that all that bugs be fixed in 1.1.2. 1.1.2 is not released yet and work on backporting security and other fixes is in progress.
New version was added to the tree. Robert the link you posted here is unavailable now, but at time you posted it here, I've showed it to mantis developers and I remember that the issues that were raised there were in TODO list for 1.1.2 release. So I can not check now but I hope that everything is fixed.
Well, link is available now and I've checked that all things reported there were fixed in 1.1.2 release, which is already stable in our tree. Please, mark this bug as appropriate. Thank you.
