We are releasing a patch for IP.Board 3.3.x and 3.4.x to address three cross-site scripting (XSS) issues.
It has been brought to our attention that specifically crafted URLs may allow an attacker to adjust another user's ignored user preferences and private message options.
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 3.3 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 3.3, 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 would like to thank rack911labs.com for bringing the private message to our attention.
