XenForo 1.5.10a Released (Includes Security Fix)

Today, we are pleased to release XenForo 1.5.10. This release fixes several bugs and issues that were found since the release of 1.5.9.

Most importantly, this release includes a fix for a security issue that we found during internal testing. The issue is known as a server-side request forgery (SSRF). This could allow an attacker to use your server to bypass your server's firewall and make internal requests. Depending on the services found, this could lead to privilege escalation or remote code execution.

This is a potentially serious issue and we strongly recommend all customers follow one of the below methods to fix this security issue.

If you are running XenForo 1.4, please see the 1.4.13 announcement for a patch. If you are running XenForo 1.3 or older, you must upgrade to the latest 1.4 or 1.5 release to fix this issue.

If you are running XenForo Media Gallery 1.0, you must also follow the instructions in the XFMG 1.0.10 release announcement to fully patch this issue. If you are running XFMG 1.1.0 to 1.1.4, you must upgrade to a newer XFMG release. XFMG 1.1.5+ will be automatically fixed by following one of the steps below.

Method 1: Upgrade to the New Version (Recommended)

You may upgrade to XenForo 1.5.10 (or any subsequent version) to fix this issue. You should upgrade as you would to any other release. See further below in this announcement for more details on this release. If you take this approach, you should not apply the patch below.

Method 2: Install the Patch (for 1.5 Users)

Download the patch zip file attached to the end of this message. It contains 4 files:

• library/XenForo/BbCode/Formatter/BbCode/AutoLink.php
• library/XenForo/Helper/Http.php
• library/XenForo/Helper/Url.php
• library/XenForo/Model/ImageProxy.php

These 4 files should be uploaded to your server, overwriting the existing files of the same names.

Note that with this method there is no outward indication that the patch has been applied. We recommend upgrading if possible.

Other Changes in 1.5.10

Some of the bugs fixed in 1.5.10 include:

• Add several language code/locale options for pages.
  
• Fix a situation where white space may not be maintained 100% when pasting code/pre-formatted into the rich text editor.
• Add a 1000 user limit to ignoring to prevent potential errors.
• Ensure that poll resetting/deleting is logged correctly.
• Automatically adjust uploaded image extensions to match their type (rather than throwing an error).
• Change NoCaptcha requests to POST to prevent a possible regular expression failure.
• Fix an issue with automatic vendor prefixing in the CSS when using @supports.
• Fix a timezone related issue when displaying stats output.
  
• Adjust the meta description of member profiles to handle missing components better.
• Prevent an error in the phpBB 3.1 importer relating to timezones.

Where necessary, the merge system within the "Outdated Templates" page should be used to integrate these changes.

Please note that we are now formally recommending that you upgrade to PHP 5.4 or newer. Our intention with XenForo 2.0 is to require PHP 5.4 or newer. If you are running PHP 5.3 or 5.2, you will receive a warning when installing or upgrading XenForo.

All customers with active licenses may now download the new version from the customer area.

More Stable

This release follows our principle that third-point (x.x.X) releases should always be more stable than the preceding version, so for the most part you will not find new features in this release. Major new features will be reserved for second point versions (x.X.x).

Installation and Upgrade Instructions

Full details for how to install and upgrade XenForo can be found in the XenForo Manual.

 

[XenForo]

We have identified a regression in 1.5.10 related to pasting content into the rich text editor. This issue can cause a paste action to fail based on the formatting of the pasted content. As such, we have patched this issue and updated the download to 1.5.10a to incorporate a fix for this issue.

If you downloaded 1.5.10a from your customer area, you do not need to take any other steps. If you are running 1.5.10 and wish to fix this bug, you may either:

1. Download 1.5.10a from your customer area and reupload the files as if you were upgrading.
2. Change the patched files manually with the versions from this bug report. Note that this approach will show these files as not containing the expected contents in the file health check.

Please note that the version will still display 1.5.10 in your admin control panel.
