CVE-2016-4357
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 Matrix Operating Environment before 7.5.1 allows remote authenticated users to obtain sensitive information or modify data via unspecified vectors, a different vulnerability than CVE-2016-2028.
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 confidenceHPE Matrix Operating Environment before version 7.5.1 contains an access control vulnerability allowing remote authenticated users to obtain sensitive information or modify data through unspecified vectors. This is distinct from CVE-2016-2028 and represents a privilege escalation or authorization bypass issue affecting the enterprise management platform.

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 Matrix Operating Environment or HP Systems Insight Manager is installedCheck the Windows registry under HKLM\SOFTWARE\Hewlett-Packard\ or look for HP SIM or Matrix OE in Add/Remove ProgramsAffected if The product is present on the system and no version is displayed or the version shown is below 7.5.1
-
Determine the installed version of HP Systems Insight ManagerOpen HP SIM (usually via Start Menu > HP > HP Systems Insight Manager) and navigate to Help > About, or check the version in Add/Remove ProgramsAffected if The version listed is 7.5 or earlier (vulnerable versions)
-
Determine the installed version of HPE Matrix Operating EnvironmentCheck the version through the product interface under Administration or System Information, or verify through Add/Remove ProgramsAffected if The version listed is 7.5 or earlier (vulnerable versions)
-
Check if the management interface is network accessibleReview firewall rules or use netstat to see if ports typically used by HP SIM (such as 23000, 23020) or Matrix OE are listening and exposedAffected if The product is exposed to network access and the version is 7.5 or earlier
A user is affected if HPE Matrix Operating Environment or HP Systems Insight Manager version 7.5 or earlier is installed and the product is network-accessible to remote authenticated users.
