CVE-2016-6117 IBM CVE debrief

CVE-2016-6117 describes an information-disclosure issue in IBM Tivoli Key Lifecycle Manager 2.5 and 2.6 where active debugging code can expose sensitive information. The NVD entry classifies the issue as network-reachable, low-complexity, and requiring no privileges or user interaction, but with confidentiality impact only. IBM’s advisory is referenced as the patch source. This is a defensive maintenance item for teams running affected TKLM deployments, especially where debug output or logging may be accessible to administrators, operators, or adjacent systems.

Who should care

IBM Tivoli Key Lifecycle Manager administrators, security engineering teams, and operations staff responsible for key-management appliances or servers running 2.5.x or 2.6.x builds listed by NVD as affected.

Technical summary

NVD maps this issue to CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and assigns CVSS v3.0 vector CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N (5.3 Medium). The vulnerable scope in the NVD record includes IBM Security Key Lifecycle Manager versions 2.5.0 through 2.5.0.7 and 2.6.0 through 2.6.0.2. The core issue is the presence of active debugging code that can disclose sensitive information; NVD does not describe integrity or availability impact for this case.

Defensive priority

Moderate priority for affected environments. Exposure is limited to confidentiality, but the lack of auth, lack of user interaction, and network attack vector make remediation important for systems handling keys or other sensitive material.

Recommended defensive actions

  • Verify whether any IBM Tivoli Key Lifecycle Manager instance is running a vulnerable 2.5.x or 2.6.x release listed in the NVD record.
  • Apply the IBM-referenced patch or vendor remediation guidance from the linked IBM advisory.
  • Review deployment settings for any debug logging, diagnostic endpoints, or verbose output that could reveal secrets.
  • Restrict administrative and service access to TKLM systems and monitor for unexpected disclosure of sensitive data in logs or responses.
  • After remediation, validate that debug functionality is disabled in production and that sensitive fields are not emitted to logs or interfaces.

Evidence notes

The debrief is based on the NVD CVE record and its linked references. NVD lists the issue as CVE-2016-6117, published 2017-02-01 and modified 2026-05-13, with CVSS v3.0 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) and CWE-200. The NVD CPE criteria enumerate affected IBM Security Key Lifecycle Manager versions 2.5.0 through 2.5.0.7 and 2.6.0 through 2.6.0.2. IBM’s support document is cited in NVD as the patch/vendor advisory reference.
