HPSBUX02249 SSRT071442 rev.2 - HP-UX Running the Ignite-UX or the DynRootDisk (DRD) get_system_info Command, Local Unqualified Configuration Change
NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.
Release Date: 2007-08-20
Last Updated: 2007-09-12
Potential Security Impact: Local unqualified configuration change
Source: Hewlett-Packard Company, HP Software Security Response Team
A potential security vulnerability has been identified in HP-UX running the Ignite-UX or the DynRootDisk (DRD) get_system_info command. This command can change system networking parameters without notification.
SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
HP-UX B.11.11, B.11.23, B.11.31 running the Ignite-UX vC.7.0, vC.7.1, vC.7.2, vC.7.3 or the DynRootDisk (DRD) vA.18.104.22.1687, vA.22.214.171.124, vA.126.96.36.1994, vA.188.8.131.522 get_system_info command.
The get_system_info command is executed by the following commands:
To determine if an HP-UX system has an affected version, search the output of "swlist -a revision -l fileset" for one of the filesets listed below. For affected systems verify that the recommended action has been taken.
action: use the script from the Resolution to work around the vulnerability
action: use the script from the Resolution to work around the vulnerability
END AFFECTED VERSIONS
Until an update is available, HP has made the following workaround procedure available to resolve the issue.
- -> Note: The script has changed. The script recommended in rev.1 of this Security Bulletin did not correctly check the HP Ignite-UX revision number. The original script would only install itself on HP Ignite-UX revision C.7.3.144. The new script documented below will work properly on all vulnerable revisions of HP Ignite-UX. Either the old or new script will work correctly with DynRootDisk.
- ->The procedure below moves the get_system_info program to another directory and replaces it with a script. The script temporarily disables the autopush program, runs the original get_system_info, and then enables autopush. By running the original get_system_info program with antopush disabled the vulnerability is avoided. More details are documented in the script.
1. Download the script "get_system_info.wrapper" from the following ftp site:
2 .Verify the cksum or md5 sum:
- ->cksum: 2284708550 5344 get_system_info.wrapper
- ->MD5 (get_system_info.wrapper) = 6ed1dfc6508e2cb45f8624a8ed31611f
- ->The new script contains this line:
# @(#) $Date: 2007-09-11 10:30:49 -0600 (Tue, 11 Sep 2007) $ $Revision: 71524 $
3. As root, copy the script into a secure directory.
4. As root, run the script. The script will display the files it is replacing.
Replacing /opt/ignite/lbin/get_system_info with $secure_directory/get_system_info.wrapper
Replacing /opt/drd/lbin/get_system_info with $secure_directory/get_system_info.wrapper
where $secure_directory is the path to the secure directory containing the script.
5. The script must be executed whenever a vulnerable version of the fileset Ignite-UX.MGMT-TOOLS or the fileset DRD.DRD-RUN is reinstalled.
MANUAL ACTIONS: Yes - NonUpdate
Use script in Resolution section to work around the vulnerability
