Flex System Chassis Management Module (CMM) and Integrated Management Module 2 (IMM2) potential security vulnerability with authentication data (CVE-2012-4838) - IBM Flex System
- Chassis Management Module's SNMPv3 and LDAP user id and passwords, Integrated Management Module 2 local passwords and private keys may be exposed to unauthorized entities as part of service or maintenance activity
CVE ID: CVE-2012-4838
Code defect may cause Flex System IBM Integrated Management Module 2 (IMM2) local accounts and IMM2 SSH and/or SSL/TLS private keys to be exposed through service or maintenance activity. It may also cause SNMPv3 and LDAP user ids and passwords which are managed by the Chassis Management Module to be exposed through service or maintenance activity.
The following Flex System IMM2 code levels may exhibit this issue:
- 1.34 (1AOO28Q)
- 1.45 (1AOO28S)
- 1.60 (1AOO32P)
Flex System Manager Update Packs which include the above builds (versions 1.1.0, 126.96.36.199, and 1.1.1)
The following CMM code levels may exhibit this issue:
All builds 1.00.0 to 1.20.2 (2PET10A to 2PET10I)
Flex System Manager Update Packs which include the above builds (versions 1.1.0 and 188.8.131.52)
CVSS Base Score: 1.9

IBM strongly recommends the following to address the potential security vulnerability:
- Apply the fix for CMM by updating to 1.40.0 (2PET10J) or later. This may be downloaded separately or found in Flex System Manager update package 1.2.0 or later.
- Apply the fix for IMM2 by updating to 1.85 (1AOO34Y) or later. (For the Flex System Manager, installing update package 1.2.0 or later will update the IMM2 on the appliance.)
- Change passwords for CMM SNMP v3 and LDAP accounts.
- Change passwords for IMM2 local accounts.
- It is also recommended to change passwords for any other accounts that use the same user id and password as any of the above accounts.
- If you would like to create new IMM2 private keys, backup the IMM2, reset it to defaults, and restore from the backup.
Please see below for information on the firmware fixes available.
