With all due respect to your team, I think they are making a mistake.
Either of these are better choices in my opinion:

1. Upgrade to the latest version of 4.1.x, which is 4.1.40. This will
   provide the least headache because you will be staying on your
   current Tomcat version, just improving your patch level.
   Plan to upgrade to a newer release of Tomcat in the future.

2. Upgrade directly to Tomcat 6 without making a stop at Tomcat 5.5.
   If you are going to upgrade major versions, there is absolutely
   no reason for you to go to Tomcat 5.5, which will eventually have
   support dropped just like Tomcat 4.1 did.

Sheesh. Did you read the CVE description?

It clearly says that Tomcat 5.5 is vulnerable through 5.5.17 (which is
inaccurate: the fix for this is documented to be in 5.5.17). Make sure
you are using a version later than that if you must use 5.5.

Now, before you ask about what version of Tomcat 6 you need in order to
avoid this vulnerability, let me help you:

1. Go to Tomcat's web site (
2. Follow the link that says "Security"
3. Pick your major Tomcat version
4. Read the fixes. Each one mentions the CVE identifier, a description
   of the problem, the versions of Tomcat affected, and the version in
   which a fix appears.

All this information is easy to find on the Tomcat web site. Please read
the documentation before continuing to ask questions such as these.
