CVE-2022-45793
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 · uneditedSysmac Studio installs executables in a directory with poor permissions. This can allow a locally-authenticated attacker to overwrite files which will result in code execution with privileges of a different user.
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 confidenceSysmac Studio installs executables in a directory with weak permissions that allow a locally-authenticated attacker to modify or replace executable files. This enables privilege escalation by achieving code execution with the privileges of another user account.

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.
-
Confirm Sysmac Studio installationSearch for Sysmac Studio in the system: check Program Files and Program Files (x86) directories for an 'Omron' folder containing Sysmac Studio, or query the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for an entry named 'Sysmac Studio'Affected if Sysmac Studio is found installed on the system
-
Identify installed versionLocate the Sysmac Studio installation directory, then find the version information: right-click the main executable (typically SysmacStudio.exe), select Properties, and check the Details tab for Product Version, or check the registry entry under the uninstall key for the DisplayVersion valueAffected if The installed version is 1.54 or lower
-
Verify directory permission vulnerabilityRight-click the Sysmac Studio installation folder (e.g., C:\Program Files\Omron\Sysmac Studio or similar), select Properties, go to the Security tab, and click Advanced. Check if Users or Authenticated Users have Write or Modify permissions granted to this folder and its contentsAffected if Non-administrator accounts (such as standard Users orAuthenticated Users) have Write, Modify, or Full Control permissions on the installation directory
The system is affected if Sysmac Studio version 1.54 or lower is installed AND the installation directory grants write/modify permissions to non-administrator users, allowing potential privilege escalation via executable replacement.

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.
dbcve · scopedFix directory permissions on the Sysmac Studio installation directory to restrict write access to only authorized administrators and the SYSTEM account, preventing unprivileged users from modifying executables.
Sysmac Studio version 1.55 or later (latest stable release)
- 1. Verify current Sysmac Studio version by opening the application and navigating to Help > Version Information
- 2. Back up any existing Sysmac Studio projects and configurations
- 3. Download the latest version of Sysmac Studio from the official OMRON download page (www.fa.omron.co.jp)
- 4. Run the installer with appropriate administrative privileges
- 5. During installation, ensure the default installation directory permissions are reviewed and restricted to authorized users only
- 6. After installation, verify the new version by checking Help > Version Information
- 7. Confirm that the installation directory has appropriate permissions (only system administrators and the installing user should have write access)
