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&gt; 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 https://exchange.xforce.ibmcloud.com/vulnerabilities/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 https://exchange.xforce.ibmcloud.com/vulnerabilities/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.
