Overview

Security issues exist in the versions of the Apache Tomcat web server that

The BlackBerry Administration Service, the BlackBerry Mobile Data System  
Connection Service, and the BlackBerry Monitoring Service use the Apache Tomcat 
web server.

These issues primarily affect the Apache Tomcat web server version that the 
BlackBerry Administration Service uses. Some minor issues impact the BlackBerry 
Mobile Data System  Connection Service and the BlackBerry Monitoring Service. 
These issues do not affect BlackBerry messaging.

Problem

The BlackBerry Enterprise Server and BlackBerry Enterprise Server Express 
products that use the vulnerable versions of the Apache Tomcat web server 
may be susceptible to the issues referenced above.

Impact

These issues may result in a Denial of Service (DoS) impacting the ability 
of the affected components to serve administration pages. There is a more 
limited potential for these issues to result in information disclosure or 
Cross-Site Scripting (XSS) on the affected components. 

Resolution

RIM has issued the following updates that resolve these vulnerabilities in 
affected versions of the BlackBerry Enterprise Server and the BlackBerry 
Enterprise Server Express. These updates replace the installed Apache Tomcat 
web server components with components that are not affected by the 
vulnerabilities. The updates for BlackBerry Enterprise Server and BlackBerry 
Enterprise Server Express versions 5.0.1 through 5.0.2 MR1 install Apache 
Tomcat web server version 6.0.28 components. The updates for BlackBerry 
Enterprise Server versions 4.1.6 and 4.1.7 install Apache Tomcat web server 
version 5.5.31 components.
