Summary
There are multiple vulnerabilities in Open Source Apache Tomcat that is used
by IBM Cognos Express. Additionally, there are multiple vulnerabilities in
IBM Runtime Environment Java Technology Edition, Version 6 that is used by
IBM Cognos Express. 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.
Vulnerability Details
CVEID:
CVE-2015-0227
DESCRIPTION:
Apache WSS4J could allow a remote attacker to bypass security restrictions,
caused by the failure to properly enforce the
requireSignedEncryptedDataElements property. An attacker could exploit this
vulnerability using various types of wrapping attacks to bypass security
restrictions and perform unauthorized actions.
CVSS Base Score: 5
CVSS Temporal Score: See
http://xforce.iss.net/xforce/xfdb/100837
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)
CVEID:
CVE-2014-0230
DESCRIPTION:
Apache Tomcat is vulnerable to a denial of service, caused by missing
limitations on request body size. By sending a specially crafted request to
the server, an attacker could keep a connection open and force Tomcat to keep
a processing thread allocated to the connection.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/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-2015-1914
DESCRIPTION:
A vulnerability in the IBM implementation of the Java Virtual Machine may
allow untrusted code running under a security manager to bypass permission
checks and view sensitive information.
CVSS Base Score: 4.3
CVSS Temporal Score: See
http://xforce.iss.net/xforce/xfdb/101908
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
CVEID:
CVE-2014-7810
DESCRIPTION:
Apache Tomcat could allow a remote attacker to bypass security restrictions,
caused by the use of expression language. An attacker could exploit this
vulnerability to bypass the protections of a Security Manager.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/103155
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/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-2015-4000
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
https://exchange.xforce.ibmcloud.com/vulnerabilities/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-2015-4748
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
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
CVEID:
CVE-2015-1931
DESCRIPTION:
IBM Java Security Components store plain text data in memory dumps, which
could allow a local attacker to obtain information to aid in further attacks
against the system.
CVSS Base Score: 2.1
CVSS Temporal Score: See
http://xforce.iss.net/xforce/xfdb/102967
for the current score

Affected Products and Versions
IBM Cognos Express 9.5.2
IBM Cognos Express 10.1.x
IBM Cognos Express 10.2.1
IBM Cognos Express 10.2.2
Remediation/Fixes
IBM Cogonos Express 10.2.1
The recommended solution is to apply the fix for versions listed as soon as
practical.
IBM Cogonos Express 10.2.1 FP4
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.
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.
IBM Cognos Express 10.2.2
IBM Cognos TM1 and IBM Cognos Business Intelligence are shipped as components
of IBM Cognos Express. Information about a security vulnerability affecting
IBM Cognos TM1 and IBM Cognos Business Intelligence
has been published in their respective Security Bulletins.
Security Bulletin: IBM Cognos TM1 is affected by multiple vulnerabilities
Security Bulletin: IBM Cognos Business Intelligence Sever 2015Q3 Security
Updater : IBM Cognos Business Intelligence Server is affected by multiple
vulnerabilities
IBM Cognos Express 9.5.2 and 10.1.x
IBM Cognos Express 9.5 and 10.1.x customers should upgrade to a more current
version and apply the corresponding update. Please contact Customer Support
with any questions.
