cyberstrikeus 10.3 Restrict manager application (Manual)
Description
Limit access to the manager application to only those with a justified need.
Rationale
Limiting access to the least privilege will ensure only those people with a justified need will have access to a resource. The manager application should be limited to only administrators.
Audit Procedure
Review $CATALINA_BASE/conf/<enginename>/<hostname>/manager.xml to determine if the RemoteAddrValve option is uncommented and configured to only allow access to systems required to connect.
Remediation
For the manager application, edit $CATALINA_BASE/conf/<enginename>/<hostname>/manager.xml, and add the bolded line:
<Context path="/manager" docBase="${catalina.home}/webapps/manager" debug="0"
privileged="true"><Valve
className="org.apache.catalina.valves.RemoteAddrValve"
allow="127.0.0.1"/></Context>
Add hosts, comma separated, which are allowed to access the admin application.
Note: The RemoteAddrValve property expects a regular expression, therefore periods and other regular expression meta-characters must be escaped.
Default Value
By default this setting is not present
