+title: WEBrick::HTTPRequest X-Forwarded-* allows arbitrary data
+date: 2019-11-25
+description: |
+  Various methods in WEBrick::HTTPRequest 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.

+       * lib/webrick/httprequest.rb (setup_forwarded_info): Parsing request
+         header failed when the request is from 2 or more Apache reverse
+         proxies. It's said that all X-Forwarded-* headers will contain more
+        than one (comma-separated) value if the original request already
+        contained one of these headers.  Since we could use these values as
+        Host header, we choose the initial(first) value. See #4922.
