CVE-2015-0138: GSKit in IBM Tivoli Directory Server (ITDS) 6.0 before 6.0.0.73-ISS-ITDS-IF0073, 6.1 before 6.1.0.66-ISS-IT...

GSKit in IBM Tivoli Directory Server (ITDS) 6.0 before 6.0.0.73-ISS-ITDS-IF0073, 6.1 before 6.1.0.66-ISS-ITDS-IF0066, 6.2 before 6.2.0.42-ISS-ITDS-IF0042, and 6.3 before 6.3.0.35-ISS-ITDS-IF0035 and IBM Security Directory Server (ISDS) 6.3.1 before 6.3.1.9-ISS-ISDS-IF0009 does not properly restrict TLS state transitions, which makes it easier for remote attackers to conduct cipher-downgrade attacks to EXPORT_RSA ciphers via crafted TLS traffic, related to the "FREAK" issue, a different vulnerability than CVE-2015-0204.

Security readout for executives and security teams

This older IBM Directory Server issue weakens TLS by allowing cipher downgrade to export-grade RSA in FREAK-related scenarios. A remote attacker who can manipulate TLS traffic could reduce connection security. The provided sources do not show CVSS, KEV listing, or active exploitation. Exposure is most likely where legacy IBM Tivoli Directory Server or IBM Security Directory Server instances still run vulnerable GSKit levels and accept TLS connections, especially over untrusted networks or internet-reachable paths. Treat as a moderate legacy exposure item. It is not shown as actively exploited in the provided sources, but directory services protect identity infrastructure and should not rely on obsolete TLS behavior. Mitigation focus: Inventory ITDS and ISDS versions and GSKit levels.; Upgrade to the IBM interim fix level named for each affected release.; Check IBM advisory guidance before applying compensating controls..
