Citrix Metaframe XP - Cross-Site Scripting

Citrix Metaframe XP is prone to cross-site scripting attacks when returning error messages to users. The error message is generated when invalid authentication credentials are transmitted to the log-in page. Exploitation of this issue could potentially result in the theft of cookie-based authentication credentials, or other attacks.
