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>.

Security readout for executives and security teams

CVE-2014-9277 affects old MediaWiki releases. A remote attacker could abuse special request handling to trigger PHP object injection. That class of issue can be serious, but the bundle provides no CVSS score and no evidence of active exploitation. Exposure is most likely in internet-facing or intranet MediaWiki instances running before 1.19.22, 1.22.14, or 1.23.7. The source bundle does not identify other affected products. Treat this as a priority legacy-platform remediation item. It is old, but any still-exposed affected MediaWiki instance represents avoidable risk on a public content system. Mitigation focus: Upgrade MediaWiki to 1.19.22, 1.22.14, 1.23.7, or a newer supported release.; Apply Debian DSA-3100 packages where MediaWiki is installed from Debian repositories.; Check Wikimedia and MediaWiki release guidance for any environment-specific upgrade notes..
