Discussion
WebCal Multiple HTML Injection and Cross-Site Scripting Vulnerabilities
WebCal is prone to multiple HTML injection and cross-site scripting vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input before using it in dynamically generated content.
Attacker-supplied HTML and script code would be executed in the context of the affected Web site, potentially allowing for theft of cookie-based authentication credentials. An attacker could also exploit the HTML injection issue to control how the site is rendered to the user; other attacks are also possible.
These issues affect version 3.04; earlier versions may also be vulnerable.
