Title: Citrix Metaframe XP Cross-site Scripting Vulnerability
Severity: MODERATE
Description:
Metaframe is a remote desktop software package distributed by Citrix. This issue affects Metaframe on the Microsoft Windows platform. The application can be configured to require authentication credentials before granting desktop access to a user.
A vulnerability has been discovered in Citrix Metaframe XP, specifically during the authentication phase. When invalid authentication credentials are supplied to the application, an error message is returned to the user. The contents of this message are included within the URI. As a result, it would be possible to include malicious script code within the page contents location of the URI, specifically within the NFuse_Message URI parameter.
This vulnerability occurs due to the Metaframe application failing to carry out sufficient sanitization of URI parameters. An attacker could potentially exploit this condition to execute arbitrary script code within the context of a victims browser. Ultimately, this could lead to the theft of cookie-based authentication credentials or other attacks.
Affected Products:
- Citrix MetaFrame 0.0.0XP
