The Solaris Management Console (smc(1M)) is a graphical user interface that provides access to Solaris system administration tools which includes a web server that runs on port 898. This SMC web server enables the HTTP TRACE method by default which may allow a local or remote unprivileged user the ability to access sensitive information, such as cookies or authentication data, contained in the HTTP headers of an HTTP TRACE request.
This issue is described in the CERT Vulnerability VU#867593 (see http://www.kb.cert.org/vuls/id/867593).
Note: The HTTP TRACE method asks a web server to echo the contents of the request back to the client for debugging purposes. The HTTP TRACE method is described in the HTTP 1.1 standard (RFC 2616, section 9.8). The TRACE method is enabled by default in Solaris Management Console (SMC) webserver.
