CKB:The internal IP address is revealed in HTTP1.0

Applies to

All versions of Cryptshare Server

---

Symptom

When requesting a page from a Cryptshare Server, the internal IP address of the server is revealed:

nc my.cryptshare.server 80

GET / HTTP/1.0

HTTP/1.1 302 Found
Date: Fri, 12 Jun 2015 07:43:06 GMT
X-Frame-Options: SAMEORIGIN
Expires: Thu, 01 Jan 1970 00:00:00 GMT
Pragma: no-cache
Cache-Control: no-cache, no-store
Location: http://10.0.1.1/Start
Content-Length: 0

---

Cause

HTTP 1.0 does not support the host-header and the Jetty Server therefore uses the server IP address instead.

---

Solution

For each Jetty configuration file (User,- and Administration Interface) an additional customizer must be added for both Http-Configurations (http,https).

1. open the Jetty XML configuration file for which the configuration shall be made
   1. user Interface: 'resources/WEB-INF/ui-config.xml'
   2. administration Interface: 'resources/WEB-INF/ai-config.xml
2. introduce a 'New'-Tag for a HostHeaderCustomizer
3. add a 'Call'-Tag for the new customizer for httpConfig-section
4. add a 'Call'-Tag for the new customizer for tlsHttpConfig-section
5. save changes
6. restart Cryptshare Server

Please edit your config files accordingly

Example config-files

This are example config files to be checked if they fit to your environment (Passwords, Cipher Suites, Ports, Names...).
Please remember to change YourServerName to the Name of your Server.
