Apache Tomcat Application Server 9 STIG:
TCAT-AS-000930
(in versions v2 r7 through v1 r1)
Title
Default error pages for manager application must be customized. (Cat III impact)
Discussion
Default error pages that accompany the manager application provide educational information on how to configure user accounts and groups for accessing the manager application. These error pages provide responses to 401 (Unauthorized), 403 (Forbidden), and 404 (Not Found) JSP error codes and should not exist on production systems.
Check Content
From the Tomcat server console, run the following command: sudo cat $CATALINA_BASE/webapps/manager/WEB-INF/jsp/401.jsp Repeat for the 402.jsp and 403.jsp files. The default error files contain sample passwords and user accounts. If the error files contained in this folder are not customized and sample information removed, this is a finding.
Fix Text
From the Tomcat server as a privileged user: sudo cd $CATALINA_BASE/webapps/manager/WEB-INF/jsp/ Use a file editor like nano or vi and edit the 401, 402, and 403 jsp files. Remove account information and make the files reflect generic error information that assists users but does not provide sample data to users. Save the file and restart Tomcat: sudo systemctl restart tomcat sudo systemctl daemon-reload
