CVE-2025-35053
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 · uneditedNewforma Info Exchange (NIX) accepts requests to '/UserWeb/Common/MarkupServices.ashx' specifying the 'DownloadExportedPDF' command that allow an authenticated user to read and delete arbitrary files with 'NT AUTHORITY\NetworkService' privileges. In Newforma before 2023.1, anonymous access is enabled by default (CVE-2025-35062), allowing an otherwise unauthenticated attacker to effectively authenticate as 'anonymous' and exploit this file upload vulnerability.
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 confidenceNewforma Info Exchange (NIX) contains an authenticated arbitrary file read/delete vulnerability in the '/UserWeb/Common/MarkupServices.ashx' endpoint. The 'DownloadExportedPDF' command does not properly validate file paths, allowing authenticated users (including anonymous users via CVE-2025-35062) to read or delete files outside the intended directory with NT AUTHORITY\NetworkService 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 Newforma Project Center installationCheck for the presence of Newforma Project Center on the system by looking for installation directories (commonly under C:\Program Files\Newforma\ProjectCenter or C:\Program Files (x86)\Newforma\ProjectCenter) or check Windows Programs and Features for 'Newforma Project Center'Affected if Newforma Project Center is installed and the version is 2024.3 or lower
-
Confirm affected version numberLocate the installed version by checking the application executable, DLL version info, or the Windows registry under HKLM\SOFTWARE\Newforma\ProjectCenter for a Version valueAffected if The installed version is 2024.3 or any version lower than 2024.3
-
Verify web service is runningCheck if IIS is running and the Newforma web application pool is active. Confirm the /UserWeb/ virtual directory exists in IIS and the MarkupServices.ashx file is present in the UserWeb\Common\ folderAffected if The web service is running and the MarkupServices.ashx endpoint is accessible
-
Check anonymous access configurationIn IIS Manager, select the Newforma website or /UserWeb application, open Authentication, and verify whether Anonymous Authentication is enabledAffected if Anonymous Authentication is enabled on the Newforma web application (this enables exploitation via CVE-2025-35062)
You are affected if Newforma Project Center version 2024.3 or lower is installed, the web interface is accessible, and users (including anonymous users) can reach the MarkupServices.ashx endpoint.

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 dataDisable anonymous access in Newforma (CVE-2025-35062) and implement strict input validation/path canonicalization on the MarkupServices.ashx endpoint to restrict file operations to authorized paths only.
