Detailed vulnerability description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to insufficient validation of user-supplied input. A remote attacker can send custom headers in an HTTP request and an HTTP 30X redirect response code, cause the application to send the custom headers to the server specified in the 'Location:' response header and  obtain potentially sensitive authentication information from applications that use custom 'Authorization:' headers.
