Security Bulletin
Summary
How the TLS Heartbleed security vulnerability applies to IBM MessageSight.
Vulnerability Details
CVE ID: CVE-2014-0160
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error in the TLS/DTLS heartbeat functionality. An attacker could exploit
this vulnerability to expose 64k of private memory and retrieve secret keys.
This vulnerability can be remotely exploited, authentication is not required
and the exploit is not complex. An exploit can only partially affect the
confidentially, but not integrity or availability.
CVSS:
CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:C/I:N/A:N)
Warning: We strongly encourage you to take action as soon as possible as
potential implications to your environment may be more serious than indicated
by the CVSS score.
Affected Products and Versions
This vulnerability is known to affect the following offerings:
IBM MessageSight Server v1.0
IBM MessageSight Server v1.1
The vulnerability does NOT affect any version or release of the following:
IBM MessageSight JMS Client
IBM MessageSight Resource Adaptor
IBM Java JSSE does not use OpenSSL.
Remediation/Fixes
The IBM MessageSight Server firmware has been updated to use a newer version
of OpenSSL, which contains a fix for the heartbleed vulnerability. An updated
firmware can be downloaded from Fix Central: 1.1.0.0-IBM-IMA-IT01015.
This fix also addresses CVE-2014-0921, CVE-2014-0922, CVE-2014-0923, and
CVE-2014-0924 as described in this technote.
After applying the fix, additional steps are recommended for CVE-2014-0160
1) Replace your SSL Certificates.
You need to revoke existing SSL certificates and reissue new certificates.
This includes IBM MessageSight server certificates uploaded using IBM
MessageSight configuration object “CertificateProfileâ€Â, and Client or CA
certificates associated with using IBM MessageSight configuration object
"SecurityProfile". You need to be sure not to generate the new certificates
using the old private key and create a new private key and use that new private
key to create the new certificate signing request (CSR).
2) Reset User Credentials
Users of network facing applications protected by a vulnerable version of
OpenSSL should be forced to reset their passwords and should revoke any
authentication or session related cookies set prior to the time OpenSSL was
upgraded and force the user to re-authenticate.

Security Bulletin
Summary
3 security vulnerabilities have been identified in IBM MessageSight V1.0 and
V1.1 allowing a remote attacker to perform a denial of service attack.
A security vulnerability has been identified in IBM MessageSight V1.0 and V1.1
allowing an attacker to log in to the server over SSH using only the first 8
characters of the password.
Vulnerability Details
DESCRIPTION:
When malformed headers are received as part of a WebSockets connection upgrade,
there is a chance that the MessageSight server process will crash and then
restart, resulting in the loss of all non-persistent messages. See APAR
IC98583.
CVSS:
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92074 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
DESCRIPTION:
Vulnerability in the code responsible for handling MQTT over WebSockets might
allow a remote attacker to consume system resources on the MessageSight server
until it is restarted. See APAR IC98692.
CVSS:
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92075 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
DESCRIPTION:
Vulnerability in the code responsible for handling MQTT authentication can
cause the MessageSight server to be restarted. See APAR IT00582.
CVSS:
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92076 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
DESCRIPTION:
IBM MessageSight contains a vulnerability that would allow a remote attacker
to bypass security. The server only checks the first 8 characters of a
password, thus ignoring any subsequent characters and giving an attacker
control over the appliance. See APAR IT00583.
CVSS:
CVSS Base Score: 4.6
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92077 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:S/C:P/I:P/A:P)
Affected Products and Versions
IBM MessageSight 1.0
IBM MessageSight 1.1
Remediation/Fixes
The recommended solution is to apply the fix to all affected versions as soon
as practical.
An updated firmware image containing the fix is available from Fix Central:
1.1.0.0-IBM-IMA-IT01015.
This fix also addresses CVE-2014-0160 as described in this technote.
