Groove Mobile Workspace vulnerable to script injection via SharePoint replicated menus

Vulnerability Note VU#514386

Original Release Date: 2005-05-19 | Last Revised: 2005-06-03


A vulnerability in the way that Groove Mobile Workspace handles SharePoint lists may allow an attacker to execute an arbitrary script.


Groove Virtual Office provides a collaborative working environment that includes shared documents, databases, and applications among other tools. Microsoft Windows SharePoint Services for Windows Server 2003 and SharePoint Team Services are used to create collaborative Web sites. A SharePoint list is a collection of information and objects displayed on a SharePoint site.

SharePoint lists that contain drop-down menus may not be properly scanned for malicious content when it is copied into the Groove Mobile Workspace. As a result, an attacker may be able to inject scripting code into the drop-down list, which may then be executed within the Groove environment.


An attacker may be able to execute arbitrary scripting code.


This vulnerability is addressed in Groove Virtual Office 3.1 build 2338, 3.1a build 2364, and Groove Workspace Version 2.5n build 1871. These updates are available from
