CVE-2014-9277

Name of the Vulnerable Software and Affected Versions MediaWiki versions prior to 1.19.22 MediaWiki versions 1.20.x through 1.22.x before 1.22.14 MediaWiki versions 1.23.x before 1.23.7

Description The issue allows remote attackers to conduct PHP object injection attacks via a crafted string containing <cross-domain-policy> in a PHP format request. This occurs because the wfMangleFlashPolicy function in OutputHandler.php causes the string length to change when converting the request to <NOT-cross-domain-policy>.

Recommendations For MediaWiki versions prior to 1.19.22, update to version 1.19.22 or later. For MediaWiki versions 1.20.x through 1.22.x before 1.22.14, update to version 1.22.14 or later. For MediaWiki versions 1.23.x before 1.23.7, update to version 1.23.7 or later.
