IBM Tivoli Directory Server (TDS) enables NULL-MD5 and NULL-SHA ciphers in the default Transport Layer Security (TLS) configuration. Use of either of these ciphers would result in unencrypted communications.
VULNERABILITY DETAILS:
**CVE ID:**CVE-2012-0726
**DESCRIPTION:**In the default TDS environment with TLS enabled, the NULL-MD5 and NULL-SHA ciphers are enabled by default. If a client failed to negotiate a stronger cipher for the TLS session, it could default to using a either a NULL-MD5 and NULL-SHA cipher. This would result in unencrypted would leave communications effectively unencrypted.
CVSS Base Score: 6.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/74303 for the current score CVSS Environmental Score*: Undefined CVSS String: (AV:N/AC:L/Au:N/C:P/I:P/A:N)
**AFFECTED PLATFORMS:**Version 6.3 and earlier
