CVE-2020-10056
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 vulnerability has been identified in License Management Utility (LMU) (All versions < V2.4). The lmgrd service of the affected application is executed with local SYSTEM privileges on the server while its configuration can be modified by local users. The vulnerability could allow a local authenticated attacker to execute arbitrary commands on the server with local SYSTEM privileges.
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 confidenceLicense Management Utility (LMU) contains a local privilege escalation vulnerability where the lmgrd service runs with SYSTEM privileges but its configuration files are writable by local authenticated users, allowing modification of the service configuration to execute arbitrary commands with highest 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 LMU installation and versionLocate the License Management Utility installation directory and check the version information (e.g., look for version file, executable properties, or installed program information). Compare the found version against the affected range of versions less than 2.4.Affected if LMU is installed with a version lower than 2.4
-
Locate the lmgrd serviceCheck Windows services list (via Services.msc or 'sc query' command) for a service named 'lmgrd' or similar license management daemon service.Affected if The lmgrd service exists on the system
-
Verify lmgrd service runs with elevated privilegesView the lmgrd service properties to confirm it is configured to run with SYSTEM or Administrator privileges.Affected if The service is configured to run with SYSTEM or highest privileges
-
Find lmgrd configuration filesSearch the LMU installation directory for configuration files associated with the lmgrd service (typically .ini, .cfg, .conf, or XML configuration files).Affected if Configuration files for lmgrd are present in the installation directory
-
Check configuration file permissionsInspect file permissions on the lmgrd configuration files (right-click > Properties > Security, or use 'icacls' command). Determine whether authenticated users or non-admin accounts have Write or Modify permissions.Affected if Authenticated non-admin users have Write or Modify permissions to lmgrd configuration files
The environment is affected if LMU version is below 2.4 AND the lmgrd service runs with SYSTEM privileges AND its configuration files are writable by local 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 data2.4
Upgrade to LMU version 2.4 or later which addresses the improper privilege assignment, or restrict filesystem permissions on lmgrd configuration files to only Administrators.
