CVE-2006-6669: n/a vulnerability

Security readout for executives and security teams

A flaw in older WebCalendar versions lets an attacker inject script or HTML through the calendar export format input. If a user follows a crafted link or loads affected content, their browser may run attacker-controlled script in the WebCalendar context. Exposure is most likely for internet-accessible or internally shared WebCalendar deployments running version 1.0.4 or earlier. Modern systems are unlikely to be affected unless they retain legacy WebCalendar instances or old distribution packages. Handle as a legacy application risk. It is not KEV-listed in the supplied data, but exposed outdated WebCalendar installations should be remediated because XSS can enable session abuse, data exposure, and phishing inside a trusted application. Mitigation focus: Inventory all WebCalendar deployments and identify versions.; Upgrade or replace WebCalendar 1.0.4 and earlier using vendor or distribution guidance.; Review Debian DSA-1279 if using Debian-packaged WebCalendar..
