Comment 1 Kurt Seifried 2011-10-12 17:39:42 EDT

Various methods in WEBrick::HTTPRequest in Ruby 1.9.2-p290 and
1.8.7-p352 and earlier and do not validate the X-Forwarded-For,
X-Forwarded-Host and X-Forwarded-Server headers in requests, which might
allow remote attackers to inject arbitrary text into log files or bypass
intended address parsing via a crafted header.

Rating is low due to limited impact (log file corruption/etc.), exploitation via another user requires man in the middle or control of a web proxy used by the user.
