Special pages, actions and views whose messages don't escape text
Open, MediumPublic


Nikerabbit made a partial list of the (main) places, in core and several extensions, containing messages which don't escape text. Each of those messages is a potential security risk.

Escape messages

@Nikerabbit or @Nemo_bis - thank you for this comprehensive list. I'm confused about one item in the "SMW/SF" section, though - the very first one:

/w/i.php?title=User:Nike&action=formedit summary

The 'summary' message is called in SF's /includes/SF_FormUtils.php, and there the two relevant lines are:

$label = wfMessage( 'summary' )->text();

Html::element( 'label', array( 'for' => 'wpSummary' ), $label ) );

I would think that the element() call does the necessary escaping; is that not true?

Maybe it is already fixed but nobody updated the bug? Currently on that URL I only see this:
Notice: Unescaped message sf-formedit-donotuseform in /www/ on line 2332

/wiki/Special:FormEdit/Support/User:Nike sf_formedit_formwarning

Change 224053 had a related patch set uploaded (by Nikerabbit):
Escape twnmp-bannerwho

Change 224053 merged by jenkins-bot:
Escape twnmp-bannerwho

@Nikerabbit - did you forgot to remove "/wiki/Special:Forms sf_forms_docu" from the list? It's the last Semantic Forms message in there; and I'm pretty sure it's now escaped.

I renamed the "SMW/SF" section to "Semantic MediaWiki".

So, I:

  • checked out and set $wgDebugMessageEscaping = true; ;
  • enabled a bunch of extensions (P2014) on a web-inaccessible mediawiki-vagrant;
  • assigned all rights to unregistered users with foreach( User::getAllRights() as $right ) { $wgGroupPermissions['*'][$right] = true; };
  • attempted to open all special pages with curl http://localhost:8080/wiki/Special:SpecialPages > /tmp/SpecialPages.html; wget -O /dev/null -i /tmp/SpecialPages.html --force-html --base=http://localhost:8080/

I'll add the messages I get logged.

Can we add this to GCI? This was the description last year:

<p><a href="">Escaping HTML is the first rule</a> for improving security against <a href="">cross-site scripting</a> attacks, which have been the most common cybersecurity threat for years, causing billions dollars of damage. In this task, you will improve the security of MediaWiki by reducing its attack surface!</p>
<p>MediaWiki provides the <a href="">Html class</a> and <a href="">i18n built-in escaping</a>, but some areas of the code don't use them correctly (or at all). You will help fixing them.</p>
<p>Pick one special page listed <a href="">in the issue tracker</a>; clone the code and check all the usages of the message keys listed next to its name; fix them and submit your patch in gerrit. The header tells the name of the repository; <a href=",n,z">examples are available</a> of how your patches should look like.</p>

Can we add this to GCI?

I'd guess so, but it would require mentor(s)...

Until January 18th I cannot guarantee fast responds.

LiquidThreads has been replaced by StructuredDiscussions on all Wikimedia production wikis (except one, which will be done soon). It is no longer under active development or maintenance, so I'm re-classifying all open LQT tasks as "Lowest" priority.

Nemo_bis raised the priority of this task from Lowest to Medium.Aug 5 2016, 7:32 AM

Change 343117 had a related patch set (by Matěj Suchánek) published:
Escape text in Linker::specialLink()

Change 343117 merged by jenkins-bot:
[mediawiki/core@master] Escape text in Linker::specialLink()

Not sure why these tags were added. It does not help me to see this open task on the board if there is nothing actionable.

How about we close this task? The list given is likely outdated already.
