CVE-2018-16207
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 · uneditedPowerAct Pro Master Agent for Windows Version 5.13 and earlier allows authenticated attackers to bypass access restriction to alter or edit unauthorized files via unspecified vectors.
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 confidencePowerAct Pro Master Agent for Windows versions 5.13 and earlier contains an access control bypass vulnerability where authenticated attackers can bypass existing restrictions to modify or edit files they should not have access to. This is an authorization flaw allowing privilege escalation through unauthorized file alterations.

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 PowerAct Pro Master Agent installationCheck for the presence of the Master Agent service on the Windows system by looking in Windows Services for 'PowerAct Pro Master Agent' or checking Program Files for Omron PowerAct Pro directories.Affected if The product is not installed on the system.
-
Determine installed versionLocate the Master Agent installation directory and check the version information. Common paths include the program's main executable or version file within the Omron PowerAct Pro folder in Program Files. Use PowerShell or right-click properties on the main executable to view version details.Affected if The installed version is 5.13 or any version lower than 5.13.
-
Verify Master Agent service statusOpen Services console (services.msc) or run 'Get-Service | Where-Object {$_.DisplayName -like "*PowerAct*"}' in PowerShell to confirm if the Master Agent service is currently running.Affected if The service is running and the version is 5.13 or earlier - the vulnerability can be exploited by authenticated users.
-
Review file permissions on Master Agent directoriesInspect NTFS permissions on the Master Agent installation directory and subdirectories. Right-click the folder, go to Properties > Security, and review which users and groups have Write or Modify permissions, especially checking for overly permissive access to standard users.Affected if Non-administrative or low-privilege authenticated users have Write or Modify access to critical Master Agent directories or configuration files.
If the Master Agent is installed, running, and the version is 5.13 or earlier, the environment is affected by this authorization bypass vulnerability that allows authenticated users to modify files outside their intended permissions.
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.
From vendor dataApply the vendor-supplied patch or upgrade to a version newer than 5.13 if available. Until a patch is released, implement compensating controls such as strict file system permissions, monitoring of the Master Agent directories, and restricting which accounts can authenticate to the service.
