CVE-2013-4572: Wikimedia Foundation MediaWiki vulnerability

CVE-2013-4572: The CentralNotice extension for MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 set...

The CentralNotice extension for MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 sets the Cache-Control header to cache session cookies when a user is autocreated, which allows remote attackers to authenticate as the created user.

Security readout for executives and security teams

A flaw in MediaWiki's CentralNotice extension could cause session cookies to be cached when a user account is autocreated. If an organization still runs the affected old MediaWiki versions, an attacker might reuse the cached session and log in as that newly created user. Exposure is most likely on legacy MediaWiki deployments using the CentralNotice extension in the affected version ranges. Publicly reachable wiki deployments have higher concern. Current exposure cannot be inferred from the bundle without asset inventory. Prioritize if any internet-facing or partner-facing MediaWiki instance remains on the affected legacy versions. If all MediaWiki deployments are modern or CentralNotice is absent, urgency drops substantially. Mitigation focus: Upgrade MediaWiki to 1.19.9, 1.20.8, 1.21.3, or a later supported release.; Confirm the CentralNotice extension is updated with the MediaWiki release.; Review Wikimedia and distribution advisories before applying any workaround..
