Sun(sm) Alert Notification
     * Sun Alert ID: 103127
     * Synopsis: Sun Fire X2100/X2200 M2 Servers ELOM Software is
       Vulnerable to Arbitrary Command Execution
     * Category: Security, Availability
     * Product: Sun Fire X2100 M2 Server, Sun Fire X2200 M2 Server
     * BugIDs: 6502439
     * Avoidance: Upgrade, Workaround
     * State: Resolved
     * Date Released: 29-Oct-2007
     * Date Closed: 29-Oct-2007
     * Date Modified: 

1. Impact

   A security vulnerability in the X2100 M2 and X2200 M2 Embedded Lights
   Out Manager (ELOM) software may allow remote unprivileged users the
   ability to execute arbitrary commands with root privileges on the
   embedded Service Processor (SP).

2. Contributing Factors

   This issue can occur on the following platforms:

   x86 Platform
     * Sun Fire X2100/X2200 M2 Servers without SP/BMC firmware version
       2.70 (or later)

   Notes:
    1. No other x64 systems are affected by this issue.
    2. The SPARC platform is not affected by this issue.

   To determine the firmware version of the SP, the ipmitool(1M) utility
   can be run as in the following example:
    $ ipmitool -H <hostname> -U <username> mc info
    Device ID                 : 5
    Device Revision           : 0
    Firmware Revision         : 2.91
    IPMI Version              : 2.0

   or the following command can be used at the CLI (logged in to the SP):
    /SP -> show /SP/AgentInfo
    /SP/AgentInfo
    ...
    Properties:
        HWVersion = 0
        FWVersion = 3.09

3. Symptoms

   There are no reliable symptoms that would indicate this issue has been
   exploited. 

4. Relief/Workaround

   To prevent this issue from occurring, administrators can restrict
   access to the SP by either connecting only via the serial port or by
   connecting the Net Mgmt RJ-45 ethernet port to a private management
   network.

   Additional information regarding management of the Sun Fire
   X2100/X2200 M2 Servers, ELOM, and ipmitool(1m) can be found in the
