Security readout for executives and security teams

CVE-2012-5395 affects the CentralAuth extension for MediaWiki. A flaw in session handling could let a remote attacker hijack a web session through the centralauth_Session cookie, putting authenticated wiki accounts at risk on affected versions. Exposure is most likely on MediaWiki installations using the CentralAuth extension on the affected 1.18, 1.19, or 1.20 release lines. Prioritize remediation for any externally reachable or business-critical wiki using CentralAuth. The main business risk is unauthorized account access, especially where wiki accounts can access sensitive operational or customer information. Mitigation focus: Upgrade affected MediaWiki deployments to 1.18.6, 1.19.3, 1.20.1, or later.; Confirm CentralAuth is updated alongside the MediaWiki core release.; Review Wikimedia security release guidance for deployment-specific notes..
