Bug 532920 (CVE-2014-9475) – <www-apps/mediawiki-{1.19.23,1.22.15,1.23.8,1.24.1}: multiple vulnerabilities (CVE-2014-{9276,9277,9475,9476,9477,9478,9479,9480,9481,9487,9507})

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Hanno Böck 2014-12-18 11:23:11 UTC]

Upstream changelog mentions a whole bunch of vulnerabilities fixed in latest releases:
* (bug T76686) [SECURITY] thumb.php outputs wikitext message as raw HTML,
  which could lead to xss. Permission to edit MediaWiki namespace is required
  to exploit this.
* (bug T77028) [SECURITY] Malicious site can bypass CORS restrictions in
  $wgCrossSiteAJAXdomains in API calls if it only included an allowed domain as
  part of its name.

== Security fixes in extensions ==
* (bug T77624) [SECURITY] Extension:Listings: missing validation in the 
  'name' and 'url' parameters.
* (bug T73111) [SECURITY] Extension:ExpandTemplates: parses user input
  as wikitext and shows a preview, yet it fails to add an edit token to
  the form and check it. This can be exploited as an XSS when 
  $wgRawHtml = true. Note this only affects the 1.19/1.22 branches.
* (bug T76195) [SECURITY] Extension:TemplateSandbox: 
  Special:TemplateSandbox needs edit token when raw HTML is allowed
* (bug T69180) [SECURITY] Extension:Hovercards: XSS in text extracts.
* (bug T73167) [SECURITY] Extension:Scribunto allows cross-origin 
  leakage of data from a wiki through timing
* (bug T71209) [SECURITY] Extension:TimedMediaHandler: Patch getid3 
  library for CVE-2014-2053.

CVE-2014-9507 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-9507):
  MediaWiki before 1.19.22, 1.20.x through 1.22.x before 1.22.14, and 1.23.x
  before 1.23.7, when $wgContentHandlerUseDB is enabled, allows remote
  attackers to conduct cross-site scripting (XSS) attacks by setting the
  content model for a revision to JS.

CVE-2014-9277 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-9277):
  The wfMangleFlashPolicy function in OutputHandler.php in MediaWiki before
  1.19.22, 1.20.x through 1.22.x before 1.22.14, and 1.23.x before 1.23.7
  allows remote attackers to conduct PHP object injection attacks via a
  crafted string containing <cross-domain-policy> in a PHP format request,
  which causes the string length to change when converting the request to
  <NOT-cross-domain-policy>.

CVE-2014-9276 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-9276):
  Cross-site request forgery (CSRF) vulnerability in the
  Special:ExpandedTemplates page in MediaWiki before 1.19.22, 1.20.x through
  1.22.x before 1.22.14, and 1.23.x before 1.23.7, when $wgRawHTML is set to
  true, allows remote attackers to hijack the authentication of users with
  edit permissions for requests that cross-site scripting (XSS) attacks via
  the wpInput parameter, which is not properly handled in the preview.

  MediaWiki 1.2x before 1.22.15, 1.23.x before 1.23.8, and 1.24.x before

  origin, as demonstrated by "http://en.wikipedia.org.evilsite.example/."

CVE-2014-9475 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-9475):

  a wikitext message.
