CVE-2025-35053

09.10.2025, 21:15

Newforma 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.

Common Weakness Enumeration

CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
