CVE-2016-2021
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 Systems Insight Manager (SIM) before 7.5.1 allows remote authenticated users to obtain sensitive information or modify data via unspecified vectors, a different vulnerability than CVE-2016-2017, CVE-2016-2019, CVE-2016-2020, CVE-2016-2022, and CVE-2016-2030.
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 Systems Insight Manager (SIM) versions prior to 7.5.1 contain a vulnerability allowing remote authenticated users to access sensitive information or modify data through unspecified vectors. This is an access control or information disclosure issue affecting authenticated users of the systems 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.
-
Verify HPE Systems Insight Manager is installedCheck for HPE SIM installation directory (typically C:\Program Files\HP\Systems Insight Manager or /opt/hp/sim) or look for the HP Systems Insight Manager service running on the systemAffected if HPE SIM is not installed on the system
-
Identify the installed HPE SIM versionLaunch HPE SIM and navigate to Help > About, or check the version in the installed software listing (Add/Remove Programs on Windows, RPM query or installation logs on Linux)Affected if The installed version is 7.5 or earlier (any version <= 7.5)
-
Confirm remote access is enabledCheck the HPE SIM web interface configuration: access https://localhost:50000 or the configured SIM port, verify remote connectivity is not restricted to localhost onlyAffected if HPE SIM is configured to accept remote network connections
-
Verify authentication is configuredExamine HPE SIM user authentication settings through the SIM web interface under Administration > Users and Groups, or check the security configuration file (typically hpSIMsecurity.xml or similar in the conf directory)Affected if User authentication is enabled and remote users can authenticate to SIM
A system is affected if HPE Systems Insight Manager or Hp Matrix Operating Environment version 7.5 or earlier is installed with remote access and user authentication enabled, allowing authenticated remote users to potentially access or modify sensitive data through the access control vulnerability.

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 dataUpgrade HPE Systems Insight Manager to version 7.5.1 or later to address the vulnerability. Restrict network access to trusted users and follow least-privilege principles for SIM user accounts.
