From Sam Reed on MediaWiki-announce. This is a security release. It is recommended you take action immediately in order to patch your MediaWiki installations.

 

This security release includes a fix for a Remote Code Execution (RCE) vulnerability present in some configurations of MediaWiki. Not everyone is impacted. To test if you are impacted by this vulnerability, after following all patch instructions in the email (including running the "composer update --no-dev" command if you are installing MediaWiki from git instead of tarball), look through your server access logs for hits to a file named "eval-stdin.php". If you see this entry in your access logs, your server may have been compromised, take additional steps to investigate and secure the server. If you need assistance in how to proceed with this, or have any difficulty checking or validating if you were impacted, post in our support forum.

I would like to announce the release of MediaWiki 1.29.2, 1.28.3 and 1.27.4!

 

These releases fix nine security issues in core and one related issue in the vendor folder. Download links are given at the end of this email.

 

Patches will be pushed to gerrit after this email is sent, and will land into the relevant branches as fast as our CI infrastructure allows. Git tags will follow soon after. All related tasks will be made public in phabricator too in the following few hours.

 

Please note that this month is the End-Of-Life date for MediaWiki 1.28. This means that MediaWiki 1.28.3 will be the last security release for that version, barring any unforeseen issues. We would strongly encourage users of MediaWiki 1.28 to upgrade to MediaWiki 1.29, released in July 2017, or a yet newer version as soon as possible. MediaWiki 1.29 will be supported until July 2018. See <https://www.mediawiki.org/wiki/Version_lifecycle> for more information.

 

This release also serves as a maintenance release for these branches.

 

== Security fixes ==

* (T128209) Reflected File Download from api.php. Reported by Abdullah Hussam. (CVE-2017-8809)

* (T165846) BotPasswords doesn't throttle login attempts.

* (T134100) On private wikis, login form shouldn't distinguish between login failure

  due to bad username and bad password. (CVE-2017-8810)

* (T178451) XSS when $wgShowExceptionDetails = false and browser sends

  non-standard url escaping. (CVE-2017-8808)

* (T176247) It's possible to mangle HTML via raw message parameter expansion.

  (CVE-2017-8811)

* (T125163) id attribute on headlines allow raw >. (CVE-2017-8812)

* (T124404) language converter can be tricked into replacing text inside tags by

  adding a lot of junk after the rule definition. (CVE-2017-8814)

* (T119158) Language converter: unsafe attribute injection via glossary rules (CVE-2017-8815)

 

The following only affects 1.29:

* (T180488) (T125177) "api.log contains passwords in plaintext" wasn't correctly fixed in all

  branches in the previous security release. (CVE-2017-0361)

 

The following only affects 1.27 and 1.28:

* (T180231) composer.json has require-dev versions of PHPUnit with known security

  issues. Reported by Tom Hutchison. (CVE-2017-9841)

 

It is recommended to run `composer update --no-dev` after upgrading to MW

1.27.4 or

1.28.3 if you installed MediaWiki via git. If you are using the tarball, you are not affected, and you do not need to run this command. This will remove developer dependancies that production wikis do not require. If you require developer dependancies, run `composer update` which will update to a version of PHPUnit without known RCE.

 

If you cannot run `composer update` for any reason, it is recommended that you delete the offending file as a minimum yourself using the following command:

 

`rm -rf vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php`

It's November 2017, which means that the 1.28.x branch of MediaWiki has reached the end of its life. Lets wish it the best as it moves off to the great big code repository in the sky. All users are encouraged to upgrade to 1.29.x which is the latest stable branch.

Note: 1.30.0 should be out by the end of the month, we've already branched and are working on making sure the release is ready-to-go :)
