The LogJam Attack on Diffie-Hellman ciphers affects IBM License Metric Tool and IBM Endpoint Manager for Software Use Analysis.
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”.

Upgrade to version 9.2.1.0 or newer.
In order to upgrade to version 9.2.1.0 or newer:
Note: In an airgapped environment, you have to run BESAirgapTool and BESDownloadCacher first in order to update your site.
In order to mitigate the vulnerability, limit the available ciphersuites using the following procedure:
enabledCiphers=“TLS_RSA_WITH_AES_128_CBC_SHA SSL_RSA_WITH_RC4_128_SHA SSL_RSA_WITH_RC4_128_MD5 TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA256 SSL_RSA_WITH_3DES_EDE_CBC_SHA TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 TLS_ECDHE_RSA_WITH_AES_
128_CBC_SHA256 TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256”
Your _ssl _stanza may look similar to the following after the change:
<ssl clientAuthenticationSupported=‘false’ id=‘defaultSSLConfig’ keyStoreRef=‘defaultKeyStore’
enabledCiphers=“TLS_RSA_WITH_AES_128_CBC_SHA SSL_RSA_WITH_RC4_128_SHA SSL_RSA_WITH_RC4_128_MD5 TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA256 SSL_RSA_WITH_3DES_EDE_CBC_SHA TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 TLS_ECDHE_RSA_WITH_AES_
128_CBC_SHA256 TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256”/>
4. Save the file and restart the server.
