Title: Citrix Program Neighborhood Agent Malicious Shortcut Creation Vulnerability
Severity: HIGH
Description:
The Citrix Program Neighborhood Agent provides server side configuration of client settings using Citrix Metaframe and NFuse.
Citrix Program Neighborhood Agent is prone to a vulnerability that could allow malicious applications to be executed on a client computer with the privileges of the current user. When the client connects to a server, the server can create shortcut files in the user's Startup folder using the directive:
<AppInStartmenu value="true" root="programs">startup</AppInStartmenu>
A malicious server can create shortcuts in the Startup folder that point to malicious applications. The next time the user starts Windows, the application the shortcut points to will be executed in the security context of the current user.
This issue was reported to affect Program Neighborhood Agent for Win32 and Citrix Metaframe Presentation Server client for WinCE.
Affected Products:
- Citrix Metaframe Presentation Server client for WinCE 8.0.0
- Citrix Program Neighborhood Agent for Win32 8.0.0
