CVE-2021-22801
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 · uneditedA CWE-269: Improper Privilege Management vulnerability exists that could cause an arbitrary command execution when the software is configured with specially crafted event actions. Affected Product: ConneXium Network Manager Software (All Versions)
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 confidenceA CWE-269 Improper Privilege Management vulnerability in ConneXium Network Manager Software allows arbitrary command execution through specially crafted event actions. The software fails to properly validate or restrict privileges when processing event action configurations, enabling an attacker to execute commands with elevated 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 ConneXium Network Manager is installedLook for the software in system registry (HKLM\SOFTWARE\Schneider Electric\ConneXium Network Manager), check for installation directory (typically C:\Program Files\Schneider Electric\ConneXium or similar), or check running processes for CNM-related executablesAffected if The software is present on the system
-
Locate the event action configuration interfaceSearch for configuration files, management console, or web interface related to event actions - typically found in the software's management console under Event/Alarm configuration sectionsAffected if Event action configuration functionality exists in the installation
-
Verify access to the event action configurationCheck if the user account accessing the system has administrative or elevated privileges to configure event actions - inspect user permissions on the management interface or configuration directoriesAffected if Users with administrative or elevated privileges can access the event action configuration interface
-
Inspect event action configuration files or logsExamine configuration files in the software's data directory for event action definitions, looking for parameters that accept command strings or executable pathsAffected if Event action configurations can be modified or created with user-supplied values
If ConneXium Network Manager is installed and the event action configuration interface is accessible to users with elevated privileges, the environment is affected by CVE-2021-22801.

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 dataRestrict administrative access to the event action configuration interface, implement strict input validation on all event action parameters, and apply network segmentation. Contact Schneider Electric for patch availability.
