Subject: Referrer log show some details about internal network

Hi,

shure not new, but an interesting kind of information disclosure of
an internal network:

http://192.168.***.***/exchange/*user1*/z_e-mails/noch_zu_erledigen
/FW:%20Doku%20fertig:%20FreeS_xF8FF_WAN-
RoadWarrior%20zu%20Check%20Point%20FW-1%20NG.EML?Cmd=open
 
http://192.168.***.***/exchange/*user2*/Inbox/FW:%20Doku%20fertig:%
20FreeS_xF8FF_WAN-RoadWarrior%20zu%20Che
ck%20Point%20FW-1%20NG.EML/1_text.htm?Security=2

Caused by an MS Exchange system?

Looks like proxies/firewalls should cut-off referrers which are
pointing to internal for privacy issue ;-)
