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 · unedited
In OSIsoft PI System multiple products and versions, a local attacker can modify a search path and plant a binary to exploit the affected PI System software to take control of the local computer at Windows system privilege level, resulting in unauthorized information disclosure, deletion, or modification.

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 confidence

This is a local privilege escalation vulnerability in OSIsoft PI System where an attacker with local access can modify a search path (DLL search order or executable path) and plant a malicious binary. When the PI System software loads the planted binary, it executes with Windows SYSTEM privileges, giving the attacker full control of the local machine with the ability to disclose, delete, or modify information.

MitigationApply vendor patches from OSIsoft for affected PI System products, restrict local file system permissions on PI System directories to prevent unauthorized modification, and follow least-privilege principles to limit local user access.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed OSIsoft PI products
    Open Windows Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' to list installed software. Look for OSIsoft PI products such as PI API, PI Buffer Subsystem, PI Connector, PI Data Archive, PI Integrator, or PI Interface Configuration Utility.
    Affected if Any OSIsoft PI product is installed and its version falls within the affected ranges (PI API <= 1.6.8.26 or <= 2.0.2.5; PI Buffer Subsystem <= 4.8.0.18; PI Connector versions up to 1.5.0.88; PI Connector Relay <= 2.5.19.0; PI Data Archive <= 3.4.430.460; PI Data Collection Manager <= 2.5.19.0; PI In
  2. Check PI System directory permissions
    Navigate to the PI System installation directory (commonly C:\Program Files\PIPC or C:\Program Files (x86)\PIPC). Right-click each subdirectory, select Properties > Security, and review which users or groups have Write or Modify permissions. Alternatively, run 'icacls "C:\Program Files\PIPC" /t' to list permissions recursively.
    Affected if Non-administrative users or groups have Write or Modify permissions on PI System directories, allowing them to plant malicious binaries in executable search paths
  3. Identify PI service account privileges
    Open Services (services.msc), locate PI-related services (such as PI Buffer Subsystem, PI Connector, PI Data Archive), right-click each service, select Properties, and note the account listed under 'Log On'. Alternatively, run 'Get-Service | Where-Object {$_.DisplayName -like "*PI*"} | Get-WmiObject Win32_Service | Select-Object Name, StartName' to list service accounts.
    Affected if PI services run under the LocalSystem account or another privileged account, and an attacker can modify search paths to hijack DLL or executable loading

Your environment is affected if any OSIsoft PI product is installed with a version within the affected ranges AND non-privileged users have write access to PI System directories where the software loads executables or DLLs.
