Security Bulletin
Summary
The Logjam Attack on TLS connections using the Diffie-Hellman (DH) key
exchange protocol affects IBM Cognos Planning
Vulnerability Details
CVEID: CVE-2015-4000
DESCRIPTION: The TLS protocol could allow a remote attacker to obtain
sensitive information, caused by the failure to properly convey a DHE_EXPORT
ciphersuite choice. An attacker could exploit this vulnerability using
man-in-the-middle techniques to force a downgrade to 512-bit export-grade
cipher. Successful exploitation could allow an attacker to recover the session
key as well as modify the contents of the traffic. This vulnerability is
commonly referred to as "Logjam".
CVSS Base Score: 4.3
CVSS Temporal Score: See

score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
Affected Products and Versions
Cognos Planning 10.1
Cognos Planning 10.1.1
Workarounds and Mitigations
The DH cipher suites must be disabled using Cognos Configuration by performing
the following actions:
1) Start Cognos Configuration.
2) Navigate to Security/Cryptography/Cognos
3) Open the supported cipher suites selection dialog.
4) Select all cipher suites that have DH in the the name and remove them from
the Current Values List. Select OK to save the new list.
5) Save and restart your service using Cognos Configuration.
You should verify applying this configuration change does not cause any
compatibility issues. Not disabling the DH stream cipher will expose yourself
to the attack described above. IBM recommends that you review your entire
environment to identify other areas where you have enabled the DH stream
cipher and take appropriate mitigation and remediation actions.

Security Bulletin
Summary
There are multiple vulnerabilities in IBM SDK Java Technology Edition, Version
6 that is used by Cognos Planning. These issues were disclosed as part of the
IBM Java SDK updates in January 2015. This bulletin also addresses the FREAK:
Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability
Vulnerability Details
CVEID: CVE-2015-0138
DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could
allow a remote attacker to downgrade the security of certain SSL/TLS
connections. An IBM SSL/TLS client implementation could accept the use of an
RSA temporary key in a non-export RSA key exchange ciphersuite. This could
allow a remote attacker using man-in-the-middle techniques to facilitate
brute-force decryption of TLS/SSL traffic between vulnerable clients and
servers.
This vulnerability is also known as the FREAK attack.
