CVE-2022-38466
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 CoreShield One-Way Gateway (OWG) Software (All versions < V2.2). The default installation sets insecure file permissions that could allow a local attacker to escalate privileges to local administrator.
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 confidenceA local privilege escalation vulnerability exists in CoreShield One-Way Gateway software versions prior to V2.2, where the default installation applies overly permissive file permissions to application files and directories. A local attacker with standard user access can modify executable files, scripts, or configuration files to gain local administrator 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.
-
Verify CoreShield One-Way Gateway installationCheck for the presence of CoreShield One-Way Gateway software on the system. Look for installation directories or applications named 'CoreShield' or 'One-Way Gateway' in common program installation locations or the system service list.Affected if The software is installed on the system
-
Determine installed versionLocate and read the application version information, typically found in the program files directory, an about dialog, or via command-line version flags. Compare the version to the affected range (versions prior to 2.2).Affected if The installed version is prior to V2.2
-
Examine application directory permissionsInspect file system permissions on the CoreShield installation directory using OS-native tools to list ACLs or permissions. Determine if standard non-admin user accounts have Write or Modify permissions to application executables, scripts, or configuration files.Affected if Non-admin users have write access to application files, scripts, or configuration files in the installation directory
A system is affected if CoreShield One-Way Gateway is installed with a version prior to 2.2 and the application directory grants write permissions to non-administrative users.
Generated from the published advisory. Verify against your own configuration.
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 · scoped2.2
Upgrade to V2.2 or later which contains corrected secure file permissions, or manually remediate by restricting file permissions on the application directory to follow least-privilege principles (remove write access for non-admin users).
V2.2
- Upgrade CoreShield One-Way Gateway software to version 2.2 or later.
- After upgrading, verify that file permissions on installation directories are properly restricted.
- Confirm that the local attacker can no longer modify privileged files to escalate privileges.
Generated from the published advisory — verify against the referenced sources before acting.
