===================================================================== CERT-Renater Note d'Information No. 2002/VULN335 _____________________________________________________________________ DATE : 11/12/2002 HARDWARE PLATFORM(S) : HP9000 Servers OPERATING SYSTEM(S) : systems running Tomcat 4.0.X versions prior to version 4.0.6. VVOS release 11.04 with only the Virtualvault A.04.60 product installed ====================================================================== ----------------------------------------------------------------- Source: HEWLETT-PACKARD COMPANY SECURITY BULLETIN: HPSBUX0212-229 Originally issued: 09 Dec 2002 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/* # C.
