658 Lotus Security Handbook Restriction: If you enable this, it is assumed you know what you’re doing, and how to protect direct access to the port at which the embedded http is listening. Figure 14-46 Remember to restart HTTP after setting HTTPEnableConnectorHeaders=1 Once this notes.ini setting is enabled, the Domino HTTP stack will look for the following special headers in HTTP requests it receives. Note: If you set the LogLevel to TRACE in the plugin XML config file, it is possible to see what headers are actually added for a given request. $WSAT: The Auth Type that is being used to make this request. $WSCC: The Client Certificate used for this request. If the value is not base64 encoded for us by the Web server, then the plug-in will base64 encode it before sending it across to the application server.
$WSCS: The cipher suite that the Web server negotiated with the client. This is not necessarily the cipher suite that the plug-in will use to send the request across to the application server. $WSIS: This header will be set to either True or False depending on whether or not the request is secure (came in over SSL/TLS). $WSSC: The scheme being used for the request. This header will normally be set to either http or https. $WSPR: The HTTP protocol level being used for this request. The plug-in currently has support for up to HTTP/1.1 requests. $WSRA: The remote IP address of the machine the client is running on. $WSRH: The remote host name of the machine the client is running on. If the hostname can't be resolved, this header should be set to the IP address. $WSRU: The remote user specified for the given request. $WSSN: The server name used for this request. This should be the value that was specified in the HOST header of the incoming request. $WSSP: The server port that the request was received on. This will be the port value that is used in route determination. $WSSI: The SSL Session ID being used for this request. If the value is not base64 encoded for us by the Web server, the plug-in will base64 encode it before sending it across to the application server. Be sure to secure the environment When utilizing this new plug-in model, it is important to stress the fact that Domino “completely” trusts the information that is sent in these special HTTP headers. For example, rather than using the client IP address recorded by the Domino HTTP stack during the HTTP request, Domino will instead trust the IP address included in the special header $WSRA. Or as another example, rather than determining the users name/etc. on its own, Domino will trust the user name provided in the $WSRU special header - as Domino will assume the user has been properly authenticated and verified by the front-end server! Thus, do not set HttpEnableConnectorHeaders=1 in your notes.ini, unless you have 100% certainty that the only traffic that can possibly arrive at your Domino server is generated by a supported front end HTTP plug-in. Otherwise, hackers can craft what appear to be authenticated requests by utilizing the special HTTP headers. Appendix C. Domino 6 HTTP plug-in hints and tips 659
