Tomcat 4.0.4 and 4.1.10 (probably all other 
earlier versions also) are vulnerable to source 
code exposure by using the default servlet
org.apache.catalina.servlets.DefaultServlet.

Solution:
Upgrade to the last releases 4.0.5 and 4.1.12
See
http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/ 
for the last releases.

Risk factor : High";
