PLATFORM: SPARC Platform * Solaris 8 * Solaris 9 without patch 116807-02 * Solaris 10 without patch 121308-01 x86 Platform * Solaris 8 * Solaris 9 without patch 116808-02 * Solaris 10 without patch 121309-01 DAMAGE: The 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. SOLUTION: Apply the available patch. ______________________________________________________________________________ VULNERABILITY The risk is LOW. Exploiting the vulnerability leads to an ASSESSMENT: information leak. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/Q-036.shtml ORIGINAL BULLETIN: http://www.sunsolve.sun.com/search/document.do? assetkey=1-26-102016-1&searchclause=102016 CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= ______________________________________________________________________________ REVISION HISTORY: 11/29/05 - updated to include changes to Sun Alert ID: 102016 that modified Contributing Factors and Resolution section. 12/27/05 - updated to include changes to Sun Alert ID: 102016 that modified State to "Resolved" and the Contributing Factors and Resolution section.

All Rights Reserved Update Date: Fri Dec 23 00:00:00 MST 2005 Status Issued Description Top Sun(sm) Alert Notification * Sun Alert ID: 102016 * Synopsis: The Solaris Management Console (SMC) Enables TRACE HTTP by Default * Category: Security * Product: Solaris 9 Operating System, Solaris 10 Operating System, Solaris 8 Operating System * BugIDs: 5090761 * Avoidance: Patch, Workaround * State: Resolved * Date Released: 26-Oct-2005, 23-Dec-2005 * Date Closed: 23-Dec-2005 * Date Modified: 28-Nov-2005, 23-Dec-2005 1. 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. 2. 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 3. Symptoms There are no predictable symptoms that would indicate the described issue has occurred. Solution Summary Top 4. Relief/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   5. Resolution This issue is addressed in the following releases: SPARC Platform * Solaris 8 with patch 111313-03 or later * Solaris 9 with patch 116807-02 or later * Solaris 10 with patch 121308-01 or later x86 Platform * Solaris 8 with patch 111314-03 or later * Solaris 9 with patch 116808-02 or later * Solaris 10 with patch 121309-01 or later Change History 28-Nov-2005: * Updated Contributing Factors and Resolution sections 23-Dec-2005: * State: Resolved * Updated Contributing Factors and Relief/Workaround sections This Sun Alert notification is being provided to you on an "AS IS" basis.
