CVE-2016-2942 IBM CVE debrief
CVE-2016-2942 describes an access-control weakness in IBM UrbanCode Deploy where an authenticated attacker with special permissions could craft a script on the server in a way that causes processes to run on a remote UrbanCode Deploy agent machine. IBM and NVD classify the issue as high severity, with potential impact to confidentiality, integrity, and availability.

Who should care
Administrators and security teams operating IBM UrbanCode Deploy, especially environments that delegate elevated deployment or scripting permissions to application users. Any organization using affected UrbanCode Deploy releases should review who can create or modify scripts and who can trigger agent-side execution.
Technical summary
The NVD record maps this issue to CWE-284 (Improper Access Control) and lists affected IBM UrbanCode Deploy versions from 6.0 through 6.2.2.1 in the supplied CPE data. The published CVSS v3.0 vector is AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating network reachability, low-privilege authentication requirements, and potentially severe business impact once the special permissions are misused.
Defensive priority
High. The flaw is not unauthenticated, but it can enable unauthorized execution on a remote agent once an attacker has the relevant account and permissions. Prioritize it in any UrbanCode Deploy deployment where script authoring or agent execution is broadly delegated.
Recommended defensive actions
- Review IBM's advisory for the vendor-recommended patch or update path and apply the supported fix for your release line.
- Audit UrbanCode Deploy roles and permissions so only explicitly authorized users can create or alter server-side scripts and trigger agent execution.
- Reduce the number of accounts with the special permissions referenced by the advisory, and remove unnecessary delegation.
- Monitor deployment and agent activity for unexpected script changes, unusual job launches, or execution initiated by accounts that do not normally use those capabilities.
- If immediate patching is delayed, apply compensating controls around privileged workflow actions and increase logging on script and agent-execution events.
