CVE-2012-4395: n/a vulnerability

Security readout for executives and security teams

CVE-2012-4395 is a cross-site scripting flaw in ownCloud before 4.0.3. A remote attacker could inject script or HTML through the redirect_url parameter. Business impact depends on whether a very old ownCloud deployment is still reachable, especially if users are authenticated through the affected interface. Exposure is most likely limited to legacy ownCloud deployments older than 4.0.3. Modern maintained ownCloud environments should not be affected unless they retain vulnerable code or unsupported forks. Prioritize if legacy ownCloud is still exposed to users or the internet. Otherwise, handle through legacy asset cleanup and vulnerability hygiene. Mitigation focus: Inventory any ownCloud deployments and confirm exact versions.; Upgrade ownCloud instances older than 4.0.3 to a fixed supported version.; Review vendor guidance and the referenced upstream commit before backporting..
