[IPS]IP.Board 3.3.x, 3.4.x and IP.Nexus 1.5.9 Security Update

Recommended Posts


We are releasing a patch for IP.Board 3.3.x and 3.4.x to address a potential cross-site scripting (XSS) issue, and we are releasing a patch for IP.Nexus 1.5.9 to address an issue where license keys may be exposed to unauthorized users. The IP.Nexus patch also includes an updated SagePay payment gateway, required for all users that use Sagepay integration as of July 31, 2015, as well as an update to the Stripe payment gateway to use their "v2" javascript integration.

It has been brought to our attention that specifically crafted files uploaded as attachments to IP.Board may allow for javascript to execute.  It has also been brought to our attention that specifically crafted URLs may allow for exposure of license keys otherwise kept private throughout IP.Nexus.

To apply the patch
Simply download the attached zip for your IP.Board version and upload the files to your forum server.


IP.Nexus 1.5.x:



IP.Board 3.4.x:



IP.Board 3.3.x:


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 3.4.8 or IP.Nexus 1.5.9 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 ESET for reporting the IP.Board XSS issue to us, and we would like to thank user "vekmor" for reporting the IP.Nexus license key exposure issue to us.
