CVE-2022-26240
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 · uneditedThe default privileges for the running service Normand Message Buffer in Beckman Coulter Remisol Advance v2.0.12.1 and prior allows non-privileged users to overwrite and manipulate executables and libraries. This allows attackers to access sensitive data.
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 confidenceThe Normand Message Buffer service in Beckman Coulter Remisol Advance v2.0.12.1 and prior runs with elevated privileges but has insecure file permissions that allow non-privileged users to overwrite and manipulate executables and libraries. This local privilege escalation vulnerability enables attackers to replace legitimate binaries with malicious ones, gaining elevated access and exposing sensitive data.

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.
-
Check Remisol Advance versionOpen Windows Control Panel > Programs and Features, or use 'wmic product get name,version' command, or check the application's About/Help section to find the installed version of Beckman Coulter Remisol AdvanceAffected if The installed version is 2.0.12.1 or any earlier version (2.0.12.1, 2.0.11.x, 2.0.10.x, etc.)
-
Identify Normand Message Buffer serviceOpen Windows Services console (services.msc) and locate the service named 'Normand Message Buffer' or search for services related to 'Remisol' or 'Normand' messagingAffected if The Normand Message Buffer service exists and is installed on the system
-
Check service executable permissionsLocate the Remisol Advance installation directory (commonly under Program Files or Program Files (x86) Beckman Coulter), right-click the folder containing the Normand Message Buffer service executable, select Properties > Security, and examine which users have Write or Modify permissionsAffected if Non-privileged users (such as standard users orAuthenticated Users) have Write or Modify access to the service executable directory
-
Check service library permissionsNavigate to the folder containing the service's DLL or library files, examine folder permissions via Properties > Security, and determine if standard users or non-admin accounts have Write permissionsAffected if Non-privileged users have Write access to directories containing service libraries that could be replaced
-
Verify service runs with elevated privilegesIn Services console, right-click the Normand Message Buffer service, select Properties, and check the 'Log on as' setting - note if it runs as SYSTEM, Administrator, or another privileged accountAffected if The service is configured to run as SYSTEM, Administrator, or a privileged account while file permissions allow write access to non-privileged users
Your environment is affected if Remisol Advance version is 2.0.12.1 or earlier AND the Normand Message Buffer service executable or library directories grant Write permissions to non-privileged users, allowing potential privilege escalation.

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 file permissions on the service executable and library directories to allow only privileged SYSTEM/Administrator accounts write access, and ensure the service follows least-privilege principles.
