[***** Start Sun Alert ID: 102828 *****] Sun(sm) Alert Notification Sun Alert ID: 102828 Synopsis: Security Vulnerability in the Sun Fire X2100M2 and X2200M2 Implementation of IPMI Category: Security Product: Sun Fire X2100 M2 Server, Sun Fire X2200 M2 Server BugIDs: 6514224 Avoidance: Upgrade State: Resolved Date Released: 07-Mar-2007 Date Closed: 07-Mar-2007 Date Modified: 26-Apr-2007 1. Impact A security vulnerability in the Sun Fire X2100M2 and Sun Fire X2200M2 implementation of IPMI may allow an unprivileged ipmitool(1m) user to gain unauthorized administrative privileges and then be able to reset or power off a local or remote Sun Fire X2100M2 or Sun Fire X2200M2 server. 2. Contributing Factors This issue can occur on the following platforms: x86 Platform * Sun Fire X2100M2 without BMC/SP Firmware 2.91 * Sun Fire X2200M2 without BMC/SP Firmware 2.91 Notes: The ipmitool(1m) is used for remote monitoring of Sun x64 systems and therefore does not affect the SPARC platform. This issue does not affect any other x64 systems apart from the Sun Fire X2100M2 and Sun Fire X2200M2. To determine the current firmware revision on the system, the following command can be run: # ipmitool -H -U -P mc info Device ID : 5 Device Revision : 0 Firmware Revision : 2.91 IPMI Version : 2.0 Manufacturer ID : 7244 Manufacturer Name : Unknown (0x1c4c) Product ID : 21305 (0x5339) Device Available : yes Provides Device SDRs : yes 3. Symptoms There are no predictable symptoms that would indicate the described vulnerability has been exploited. Solution Summary Top 4. Relief/Workaround There is no workaround for this issue. Please see the Resolution section below. 5. Resolution This issue is addressed on the following platforms: x86 Platform * Sun Fire X2100M2 with BMC/SP Firmware 2.91 (included with M2 Server 1.4 CD ISO release) at http://www.sun.com/servers/entry/x2100/downloads.jsp * Sun Fire X2200M2 with BMC/SP Firmware 2.91 (included with M2 Server 1.4 CD ISO release) at http://www.sun.com/servers/x64/x2200/downloads.jsp Change History 26-Apr-2007: Revised Synopsis and Impact section This Sun Alert notification is being provided to you on an "AS IS" basis.
