 SSRT2430 Security Vulnerability in Tomcat 4.0.X
 -----------------------------------------------------------------

NOTICE: There are no restrictions for distribution of this Bulletin
provided that it remains complete and intact.

The information in the following Security Bulletin should be
acted upon as soon as possible. Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.

 ------------------------------------------------------------------
PROBLEM: Security vulnerability in Tomcat 4.0.X versions prior
         to version 4.0.6.

IMPACT: Potential unauthorized source code listing.

PLATFORM: HP9000 Servers running VVOS release 11.04 with only
           the Virtualvault A.04.60 product installed.

SOLUTION: Upgrade to Tomcat 4.0.6 or later Tomcat 4.0.X version,
           or disable the affected resource manually (see below).

MANUAL ACTIONS: Yes - NonUpgrade
                 On VVOS 11.04 only, if one of the Tomcat
                 4.0.X versions prior to 4.0.6 is integrated
                 with Apache web server, comment the lines
                 in configuration files as specified below.

AVAILABILITY: n/a

 ------------------------------------------------------------------

 A. Background
    This is only applicable for customers who have downloaded
    and integrated Tomcat 4.0.X with their Virtualvault platform.

    Virtualvault A.04.60 has been released with the support for
    the integration of Tomcat 4.0.X versions with the Apache web
    server. The default servlet
    (org.apache.catalina.servlets.DefaultServlet) in Tomcat
    versions prior to 4.0.6 exposes the source code of server
    files via a direct request to the servlet.

 B. Recommended solution

    Hewlett-Packard recommends the customers who have installed
    Virtualvault A.04.60 and integrated Tomcat 4.0.X versions prior
    to 4.0.6 with Apache web server, to follow either of the
    instructions given below.

    1. Upgrade Tomcat to version 4.0.6 or later Tomcat 4.0.X
       version. (This is the preferred solution). Tomcat 4.0.6
       can be found at:

http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.6/bin
/

    2. Customers who cannot upgrade Tomcat as recommended above
       should implement either of the following manual workaround
       solutions to prohibit users from exploiting this
       vulnerability:

     2.1. Configure Tomcat to deny access to the
          "/servlet/org.apache.catalina.servlets.DefaultServlet/*"
          resource.

       or

     2.2 Comment the following lines in the applications'
         configuration files by prefixing a '#':
           #
           # invoker
           # /servlet/*
           #
