WebCalendar is prone to multiple HTML-injection and cross-site scripting vulnerabilities because the application fails to properly sanitize user-supplied input before using it in dynamically generated content.
Attacker-supplied HTML and script code would run in the context of the affected site, potentially allowing an attacker to steal cookie-based authentication credentials. The attacker could also exploit the HTML-injection issues to control how the site is rendered to the user; other attacks are also possible.
These issues affect WebCalendar 1.1.6; other versions may also be vulnerable.
