We are releasing a patch for IP.Board 3.3.x and 3.4.x to address two CSRF issues and one XSS issue.
It has been brought to our attention that a cross site request forgery issue exists with gravatar images that can allow a potential attacker to cause a user to store a gravatar profile photo that was not desired. Further, during internal reviews of the issue we discovered another CSRF issue that can allow an attacker to mark all private messages as read. Finally, a minor "self XSS" issue has also been patched with this update.
To apply the patch
Simply download the attached zip for your IP.Board version and upload the files to your forum server.
If you are an IPS Community in the Cloud client running IP.Board 3.4 or above, no further action is necessary as we have already automatically patched your account. If you are using a version older than IP.Board 3.4, you should contact support to upgrade.
If you install or upgrade to IP.Board 3.4.7 after the date and time of this post, no further action is necessary as we have already updated the main download zips.
We extend our thanks to Daniel Price, A.K.A ShadeSpeed of the GameMaker Community for notifying us of the gravatar issue privately and promptly.
