CVE-2019-18271
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 · uneditedOSIsoft PI Vision, All versions of PI Vision prior to 2019. The affected product is vulnerable to a cross-site request forgery that may be introduced on the PI Vision administration site.
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 confidenceThis is a cross-site request forgery (CSRF) vulnerability affecting the PI Vision administration site in all versions prior to 2019. The vulnerability allows attackers to trick authenticated administrators into performing unintended administrative actions on the PI Vision system via malicious requests.

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.
-
Identify if OSIsoft PI Vision is installedCheck the installed applications or programs list on the system for OSIsoft PI Vision, or check the IIS/sites configuration if hosted on IISAffected if PI Vision is present on the system
-
Determine the installed PI Vision versionLocate the PI Vision version information typically found in the application itself (help/about section), installation directory, or PI Vision configuration filesAffected if The version is any release prior to the 2019 release (versions < 2019)
-
Confirm PI Vision administration interface accessibilityVerify that the PI Vision administration site (typically at /admin or /PIVisionAdmin paths) is accessible via the web serverAffected if The admin interface is accessible and the application is running
-
Verify CSRF token implementation on admin formsInspect the HTML source of administrative forms in PI Vision to check for the presence of anti-CSRF token fields (such as hidden input fields with token values)Affected if Administrative forms lack CSRF token fields or tokens are not validated server-side (requires code review or penetration testing to confirm)
You are affected if PI Vision is installed and the version is prior to 2019, and the admin interface is accessible without proper CSRF token protection on state-changing requests.

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 data2019
Implement anti-CSRF tokens on all administrative forms and validate these tokens server-side for every state-changing request in the PI Vision administration interface.
