CVE-2016-6125 IBM CVE debrief

Who should care

Administrators and security owners responsible for IBM Kenexa LMS on Cloud deployments, especially environments where users can interact with the Web UI and where browser sessions carry sensitive access.

Technical summary

NVD classifies the weakness as CWE-79 and lists the CVSS v3.0 vector as AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. That means the issue is remotely reachable, requires low privileges and user interaction, changes scope, and can impact confidentiality and integrity at a limited level without affecting availability. The vulnerable product coverage in the NVD record includes IBM Kenexa LMS on Cloud 13.1, 13.2, 13.2.2, 13.2.3, and 13.2.4.

Defensive priority

Medium. The issue is exploitable only with user interaction and low privileges, but it can still affect trusted browser sessions and potentially disclose credentials. Prioritize if the application is internet-facing or used by many authenticated users.

Recommended defensive actions

• Review the IBM PSIRT advisory referenced by NVD for vendor remediation guidance.
• Update or remediate any affected IBM Kenexa LMS on Cloud deployments listed in the NVD record: 13.1, 13.2, 13.2.2, 13.2.3, and 13.2.4.
• Audit the Web UI for unescaped user-controlled content and validate that server-side and client-side output encoding is consistently applied.
• Use session hardening measures such as secure cookie handling and shorter session lifetimes where appropriate.
• Monitor for suspicious browser-side behavior or unexpected script injection reports from users.
• Confirm whether any compensating controls, such as content security policy, are available and practical in the deployment.

Evidence notes
