13.5.1. Removing Unused Interfaces from web.xml (CA Only)
Copiar o link

Several legacy interfaces (for features like bulk issuance or the policy framework) are still included in the CA's web.xml file. However, since these features are deprecated and no longer in use, then they can be removed from the CA configuration to increase security.
  1. Stop the CA. 
    # systemctl stop pki-tomcatd@instance_name.service
    Copy to Clipboard Toggle word wrap
    OR (if using nuxwdog watchdog) 
    # systemctl stop pki-tomcatd-nuxwdog@instance_name.service
    Copy to Clipboard Toggle word wrap
  2. Open the web files directory for the CA. For example: 
    # cd /var/lib/pki/instance_name/ca/webapps/ca/WEB-INF
    Copy to Clipboard Toggle word wrap
  3. Back up the current web.xml file. 
    # cp web.xml web.xml.servlets
    Copy to Clipboard Toggle word wrap
  4. Edit the web.xml file and remove the entire <servlet> entries for each of the following deprecated servlets:
    • caadminEnroll
    • cabulkissuance
    • cacertbasedenrollment
    • caenrollment
    • caProxyBulkIssuance
    For example, remove the caadminEnroll servlet entry: 
    <servlet>
      <servlet-name>  caadminEnroll  </servlet-name>
      <servlet-class> com.netscape.cms.servlet.cert.EnrollServlet
</servlet-class>
             <init-param><param-name>  GetClientCert  </param-name>
                         <param-value> false       </param-value> </init-param>
             <init-param><param-name>  successTemplate  </param-name>
                         <param-value> /admin/ca/EnrollSuccess.template
</param-value> </init-param>
             <init-param><param-name>  AuthzMgr    </param-name>
                         <param-value> BasicAclAuthz </param-value>
</init-param>
             <init-param><param-name>  authority   </param-name>
                         <param-value> ca          </param-value> </init-param>
             <init-param><param-name>  interface   </param-name>
                         <param-value> admin          </param-value>
</init-param>
             <init-param><param-name>  ID          </param-name>
                         <param-value> caadminEnroll </param-value>
</init-param>
             <init-param><param-name>  resourceID  </param-name>
                         <param-value> certServer.admin.request.enrollment
</param-value> </init-param>
             <init-param><param-name>  AuthMgr     </param-name>
                         <param-value> passwdUserDBAuthMgr </param-value>
</init-param>
   </servlet>
    Copy to Clipboard Toggle word wrap
  5. After removing the servlet entries, remove the corresponding <servlet-mapping> entries. 
    <servlet-mapping>
      <servlet-name>  caadminEnroll  </servlet-name>
      <url-pattern>   /admin/ca/adminEnroll  </url-pattern>
</servlet-mapping>
    Copy to Clipboard Toggle word wrap
  6. Remove three <filter-mapping> entries for an end-entity request interface. 
       <filter-mapping>
      <filter-name>  EERequestFilter              </filter-name>
      <url-pattern>  /certbasedenrollment         </url-pattern>
   </filter-mapping>

   <filter-mapping>
      <filter-name>  EERequestFilter              </filter-name>
      <url-pattern>  /enrollment                  </url-pattern>
   </filter-mapping>

   <filter-mapping>
      <filter-name>  EERequestFilter              </filter-name>
      <url-pattern>  /profileSubmit               </url-pattern>
   </filter-mapping>
    Copy to Clipboard Toggle word wrap
  7. Start the CA again. 
    # systemctl start pki-tomcatd@instance_name.service
    Copy to Clipboard Toggle word wrap
    OR (if using nuxwdog watchdog) 
    # systemctl start pki-tomcatd-nuxwdog@instance_name.service
    Copy to Clipboard Toggle word wrap
