CVE-2016-6084 IBM CVE debrief

Who should care

IBM BigFix Platform operators and administrators running affected 9.0 or 9.1 deployments, especially where BES server access is reachable from adjacent or otherwise less-trusted internal networks.

Technical summary

The NVD entry classifies the issue as CVE-2016-6084 with CVSS 3.0 vector AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, reflecting a network-adjacent, low-complexity crash condition. NVD lists affected IBM BigFix Platform versions 9.0 and 9.1, and the weakness is mapped to CWE-20 (improper input validation).

Defensive priority

Medium. This is an availability issue rather than a code-execution flaw, but it can still disrupt BigFix operations if the BES server is reachable from adjacent networks.

Recommended defensive actions

• Check whether any IBM BigFix Platform 9.0 or 9.1 deployments are still in service.
• Review IBM's vendor advisory and apply the referenced patch or mitigation for CVE-2016-6084.
• Restrict network reachability to the BES server, especially from adjacent or less-trusted internal segments.
• Validate that segmentation, firewall rules, and administrative access controls prevent unnecessary XMLSchema request exposure.
• Monitor BigFix server logs and service health for unexpected crashes or repeated failures.

Evidence notes

The source corpus describes IBM BigFix Platform as vulnerable to a crash of the BES server when an attacker on the local network sends a specially crafted XMLSchema request. NVD assigns CVSS 3.0 AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H and maps the issue to CWE-20. The affected CPE criteria in the record are IBM BigFix Platform 9.0 and 9.1. References in the record point to IBM's advisory/patched guidance and a SecurityFocus entry. CVE publication date used here is 2017-02-01, with an NVD record modification noted on 2026-05-13.
