CVE-2016-4386
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHPE Network Automation Software 10.10 allows local users to write to arbitrary files via unspecified vectors.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceLocal privilege escalation vulnerability in HPE Network Automation Software 10.10 allows authenticated local users to write to arbitrary files on the system via unspecified vectors. This could enable an attacker to achieve complete system compromise by overwriting critical system files, configuration files, or escalating privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if HPE Network Automation is installedCheck for HPE Network Automation software on the system. Look for the software in installed programs list, or check for the application directory typically under C:\Program Files\HPE\Network Automation or /opt/hp/na depending on OS.Affected if HPE Network Automation software is found on the system
-
Determine the installed versionUse the software's built-in version display feature, check the About section in the application UI, or look for version information in the installation directory files.Affected if The installed version is exactly 10.10
-
Verify the service is runningCheck if the HPE Network Automation service or daemon is active. On Windows, check Services control panel or run 'sc query' for NA service. On Linux, check running processes for na or networkautomation entries.Affected if The HPE Network Automation service is running and accessible
-
Assess local user accessReview local user accounts on the system that have credentials to authenticate to HPE Network Automation. Check which users have local system access.Affected if There are local authenticated users beyond trusted administrators who can access the system
A system is affected if HPE Network Automation version 10.10 is installed and running, and local authenticated users with untrusted access exist on that system.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch from HPE for this vulnerability; if unavailable, restrict local system access to trusted personnel only and monitor for suspicious file system modifications.
