CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101995 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-0488
DESCRIPTION: Server applications which use the IBM Java Secure Socket Extension provider to accept SSL/TLS connections are vulnerable to a denial of service attack due to an unspecified vulnerability.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/102336 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-2808
Description: The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as "Bar Mitzvah Attack".
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101851 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
For more details, refer the technote at 1702789
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)
For more details, refer the technote at 1959284
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.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/100691 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

Remediation/Fixes
Replace the JRE used in IBM RLKS Administration and Reporting Tool and IBM RLKS Administration Agent.
Steps to replace the JRE in IBM RLKS Administration and Reporting Tool (All Versions)
1. Go to Fix Central
2. On the Find product tab, enter Rational Common Licensing in the Product Selector field and hit enter.
3. Select the Installed Version and hit continue button.
4. Select the platform of the machine where RLKS Administration and Reporting Tool is installed and hit continue button.
5. On the Identify fixes page, select Browse for fixes and select Show fixes that apply to this version and hit continue button.
6. Download the Java runtime iFix for RLKS Administration and Reporting Tool.
Note: Although the name of the iFix is RLKS_Administration_And_Reporting_Tool_8148_Admin_iFix_1_<Platform>_<Architecture>, the same ifix is applicable to all previous RLKS Administration and Reporting Tool versions.
7. Shutdown RLKS Administration and Reporting Tool.
8. Go to the installation location of RLKS Administration and Reporting Tool.
9. Rename <install location>/server/jre folder to <install location>/server/jre_back.
This step backs up the existing JRE.
10. Extract the downloaded JRE into <install location>/server/ folder
Example: <install location>/server/jre
11. Startup RLKS Administration and Reporting Tool.
12. Login to the tool using rcladmin user and verify that you see the configured license servers under 'Server' tab.
