CVE-2016-0206 IBM CVE debrief

CVE-2016-0206 is a low-severity availability issue in IBM Cloud Orchestrator. According to NVD, a local authenticated attacker can use a specially crafted, malformed URL to cause the server to slow down for a short period of time. The issue was published on 2017-02-08 and is mapped by NVD to IBM Cloud Orchestrator versions 2.3, 2.3.0.1, 2.4, 2.4.0.1, and 2.4.0.2.

Who should care

IBM Cloud Orchestrator administrators and operators running the affected versions, especially environments where authenticated local users can interact with the application.

Technical summary

NVD assigns CVSS 3.0 vector AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L with CWE-20 (Improper Input Validation). The described behavior is an application slowdown rather than a data exposure or integrity issue, and the attacker must already have local authenticated access. The vendor reference in the NVD record points to an IBM support advisory/patch notice.

Defensive priority

Low. This is a localized, authenticated availability issue with limited impact, but it should still be patched on affected IBM Cloud Orchestrator deployments because it is trivially reachable once the attacker is authenticated.

Recommended defensive actions

  • Apply the IBM fix or patch referenced by the vendor advisory in the NVD record.
  • Confirm whether any Cloud Orchestrator instances run affected versions 2.3, 2.3.0.1, 2.4, 2.4.0.1, or 2.4.0.2.
  • Restrict local authenticated access to trusted administrative users and review account permissions.
  • Validate and harden URL/input handling in front of the application where operationally possible.
  • Monitor for repeated malformed-request patterns that correlate with performance degradation.
