CVE-2018-9066
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 · uneditedIn Lenovo xClarity Administrator versions earlier than 2.1.0, an authenticated LXCA user can, under specific circumstances, inject additional parameters into a specific web API call which can result in privileged command execution within LXCA's underlying operating system.
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 · high confidenceThis is an authenticated command injection vulnerability in Lenovo xClarity Administrator. An authenticated user can inject additional parameters into a specific web API call, allowing execution of privileged commands on the underlying operating system. The vulnerability stems from insufficient input validation in the API endpoint.

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 Lenovo XClarity Administrator is deployedLocate the XClarity Administrator instance in your environment. This is typically a web-based systems management tool that runs on a server and exposes a web interface on port 443 or 8443 by default. Check your inventory of deployed systems management software.Affected if Lenovo XClarity Administrator is present in your environment
-
Determine the installed versionAccess the XClarity Administrator web interface and navigate to the About or System Information page typically found in the administration or settings section. The version is usually displayed on this page. Alternatively, check the installation directory for version information if you have direct server access.Affected if The installed version cannot be determined or is displayed as a version prior to 2.1.0
-
Compare version against the affected rangeIf you obtained a version number, verify whether it is less than 2.1.0. For example, versions such as 2.0.x, 1.x.x, or any build prior to the 2.1.0 release are within the affected range.Affected if The installed version is any release prior to 2.1.0 (e.g., 2.0.0 through 2.0.5)
-
Verify API access is enabledConfirm that the XClarity Administrator web API is accessible. The vulnerability is exploitable through the web API endpoint. Check whether the API service is running and network-accessible to your users or systems.Affected if The XClarity Administrator API is accessible and authentication is enabled, allowing authenticated users to make API calls
You are affected if Lenovo XClarity Administrator is installed with a version lower than 2.1.0 and the API is accessible to authenticated users.

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 data2.1.0
Upgrade Lenovo xClarity Administrator to version 2.1.0 or later to receive the vendor patch that addresses the parameter injection. If immediate patching is not possible, restrict API access to trusted users only and monitor for suspicious API activity.
