<bug_description>Two sample CGI's supplied with FastCGI are vulnerable to cross-site scripting attacks. FastCGI is an 'open extension to CGI that provides high performance without the limitations of server specific APIs', and is included in the default installation of the 'Unbreakable' Oracle9i Application Server. Various other web servers support the FastCGI extensions (Zeus, Pi3Web etc). Two sample CGI's are installed with FastCGI, (echo.exe and echo2.exe under Windows, echo and echo2 under Unix). Both of these CGI's output a list of environment variables and PATH information for various applications. They also display any parameters that were provided to them. Hence, a cross site scripting attack can be performed via a request.</bug_description>
