"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
as-yet unspecified buffer overflow that is triggered when processing a
specially crafted request.  An unauthenticated, remote attacker can
leverage this issue to execute arbitrary code on the remote host. 

Note that Nessus has not tried to exploit this issue but rather has
only checked the affected plug-in's change number / build timestamp." );
