Security Bulletin
Summary
There are multiple vulnerabilities in IBM Runtime Environment Java Technology
Edition, Version 6 and IBM Runtime Environment Java Technology Edition,
Version 7 that are used by IBM Cognos Business Intelligence. These issues were
disclosed as part of the IBM Java SDK updates in July 2015.
This bulletin also addresses LOGJAM: The TLS protocol could allow a remote
attacker to obtain sensitive information, caused by the failure to properly
convey a DHE_EXPORT ciphersuite choice.
As the length of the server key size are increased, the amount of CPU required
for full TLS/SSL handshake can significantly increase. Please carefully test
and assess the impact to your CPU requirements to ensure sufficient CPU
resources, otherwise the system availability may be impacted.
You should verify applying this configuration change does not cause any
compatibility issues. If you change the default setting after applying the
fix, you 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 Diffie-Hellman key-exchange protocol used in TLS and take
appropriate mitigation and remediation actions.
A security vulnerability has been discovered in Apache Tomcat that was
reported in the 04/09/2015 X-Force Report.
OpenSSL vulnerabilities were disclosed on June 9, 2015 by the OpenSSL Project.
OpenSSL is used by IBM Cognos Business Intelligence. The CVE's applicable to
IBM COGNOS Business intelligence have been addressed.
Vulnerability Details
CVEID: CVE-2014-0230
DESCRIPTION: Apache Tomcat is vulnerable to a denial of service, caused by an
error when uploading files. An attacker could exploit this vulnerability to
consume all available memory resources.
CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/102131 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
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 http://xforce.iss.net/xforce/xfdb/103294 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
CVEID: CVE-2015-1969
DESCRIPTION: IBM Cognos Business Intelligence is vulnerable to cross-site
scripting, caused by improper validation of user-supplied input. A remote
attacker could exploit this vulnerability using a specially-crafted URL to
execute script in a victim's Web browser within the security context of the
hosting Web site, once the URL is clicked. An attacker could use this
vulnerability to steal the victim's cookie-based authentication credentials.
CVSS Base Score: 3.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/103607 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:S/C:N/I:P/A:N)
CVEID: CVE-2015-2625
DESCRIPTION: An unspecified vulnerability related to the JSSE component could
allow a remote attacker to obtain sensitive information.
CVSS Base Score: 2.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/104743 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:N/A:N
CVEID: CVE-2015-4748
DESCRIPTION: An unspecified vulnerability related to the Security component
has complete confidentiality impact, complete integrity impact, and complete
availability impact.
CVSS Base Score: 7.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/104729 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:C/I:C/A:C)
CVEID: CVE-2015-4749
DESCRIPTION: An unspecified vulnerability related to the JNDI component could
allow a remote attacker to cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/104740 for the current
score
CVSS Environmental Score*: Undefined
