page that doesn't exist in the tomcat server, or when an existing tomcat web.xml error-page page returns an error, the tomcat server will display the version number as shown below. This might be tomcat custom error page a security risk, especially if you are running an old Tomcat server that has some known exploits. For some reason, if you can't upgrade the Tomcat server to the http://stackoverflow.com/questions/794329/disable-all-default-http-error-response-content-in-tomcat latest version, and you just want to hide the version number from the error pages, do the steps mentioned below. Go to $CATALINA_HOME/lib, and create the org/apache/catalina/util directory under here. In the following example, /home/tomcat is the $CATALINA_HOME cd /home/tomcat/lib mkdir -p org/apache/catalina/util Go to this newly created directory, and create a ServerInfo.properties file, and add the server.info parameter as http://www.thegeekstuff.com/2013/08/hide-tomcat-version-number/ shown below. Set the value of this parameter to anything you like. cd org/apache/catalina/util $ vi ServerInfo.properties server.info=Apache Tomcat Version X Afer this restart the tomcat server. cd $CATALINA_HOME/bin ./catalina.sh stop ./catalina.sh start Now, if you go the error page, you'll not see the tomcat version number. Instead, you'll see the text you've set for the server.info parameter. After you do the above, if you want to see the Tomcat version number, you can still do it from the command line, using the version.sh script as shown below. $ $CATALINA_HOME/bin/version.sh ..

from two separate blog entries of mine involving the removal of information disclosure vulnerabilities in Apache Tomcat. Although centered around Tomcat http://www.techstacks.com/howto/suppress-server-identity-in-tomcat.html versions 6.0 and 7.0, these techniques can also be applied to JBoss. Introduction Information Disclosure vulnerabilities are issues that provide an attacker with configuration and/or version details http://www.tomcatexpert.com/knowledge-base/suppressing-stack-traces-http-500-errors on the web container or web applications running inside the container. The concern these details raise is that the more information the attacker has about your web error page application or app server, the easier it is for the attacker to come up with ways to breach the service. The most common types of information disclosure vulnerabilities associated with tomcat found by security auditors and scanning utilities are those that list server type and server version information. The two most-frequently reported information disclosure vulnerabilities how do i involve the Tomcat version being reported in the Server HTTP Response header and default error pages that report server type and version details. How To Modify the Server Header You can modify your tomcat server.xml and add a "server" option and set it to whatever you want. The server option should be set for any http or ssl connectors that you have running. For example, below is a sample HTTP Connector configuration from an example server.xml file:
HTTP 500 Errors Suppressing Stack Traces on HTTP 500 Errors posted by SpringSource on May 18, 2010 04:33 AM Security Audits may identify issues with 500 errors, and require the stack traces to be suppressed. By default when a 500 error (Internal Server Error) occurs in Tomcat it will display a full stack trace on the error page. This can give a hacker information about what technology is being used within the application. To control the error response, it is recommended to customize your own error reporting valve. The current error reporting valve is a good starting point and can be modified to meet your needs. To remove the stack trace element alone will mean removing two lines of code. Here is the source to the current valve: http://svn.apache.org/viewvc/tomcat/tc6.0.x/trunk/java/org/apache/catalina/valves/ErrorReportValve.java?view=markup The docs for how to configure it are: http://tomcat.apache.org/tomcat-6.0-doc/config/host.html For more than 10 years, SpringSource employees have been supporting Apache technologies, with unparalleled experience and commitment to the Apache Software Foundation. More than 400 of the Fortune 500 count on SpringSource to support their mission-critical business applications. Leaders of the Apache Software Foundation, including Board Members, work at SpringSource and dedicate a significant amount of time further developing the Apache Tomcat open source project. Over the last 2 years, 95% of the issues fixed in the Apache Tomcat project were fixed by SpringSource engineers.
