Solaris 9 Operating System
Solaris 10 Operating System
Solaris 8 Operating System
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.
This issue can occur in the following releases:
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
There are no predictable symptoms that would indicate the described issue has occurred.
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
This issue is addressed in the following releases:
