Overview

thin is a thin and fast web server.

Affected versions of this package are vulnerable to Improper Input Validation. lib/thin/connection.rb relies on the X-Forwarded-For header to determine the IP address of the client, which allows remote attackers to spoof the IP address and hide activities via a modified X-Forwarded-For header.
