Bug Id
5090761

Impact

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.

Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• Solaris 8 without patch 111313-03
• Solaris 9 without patch 116807-02
• Solaris 10 without patch 121308-01

x86 Platform

• Solaris 8 without patch 111314-03
• Solaris 9 without patch 116808-02
• Solaris 10 without patch 121309-01

The described issue only occurs if the Solaris Management Console (smc(1M)) is running on the system.

This can be determined by running the following command as the "root" user:

    # /etc/init.d/init.wbem status
    Solaris Management Console server not running on port 898
# /etc/init.d/init.wbem status
Solaris Management Console server version 2.1.0 running on port 898

Symptoms

There are no predictable symptoms that would indicate the described issue has occurred.

Workaround

The Trace method cannot be turned off. To workaround this issue until patches can be applied, sites may disable the Solaris Management Console (smc(1M)) by running the following command as the root user:

To stop the running of the smc(1M) server:

    # /etc/init.d/init.wbem stop

To prevent the smc(1M) server from starting upon successive reboots:

    # mv /etc/rc2.d/S90wbem /etc/rc2.d/disabled-S90wbem
