Description

Newforma Info Exchange (NIX) '/UserWeb/Common/MarkupServices.ashx' 'StreamStampImage' accepts an encrypted file path and returns an image of the specified file. An authenticated attacker can read arbitrary files subject to the privileges of NIX, typically 'NT AUTHORITY\NetworkService', and the ability of StreamStampImage to process the file. The encrypted file path can be generated using the shared, hard-coded secret key described in CVE-2025-35052. This vulnerability cannot be exploited as an 'anonymous' user as described in CVE-2025-35062.

Attack-Flow Graph

Executive Summary

This vulnerability exists in Newforma Info Exchange (NIX) at the endpoint '/UserWeb/Common/MarkupServices.ashx' in the 'StreamStampImage' function. It accepts an encrypted file path and returns an image of the specified file. An authenticated attacker who has privileges in NIX (typically 'NT AUTHORITY\NetworkService') can exploit this to read arbitrary files that StreamStampImage can process. The encrypted file path can be generated using a shared, hard-coded secret key described in another vulnerability (CVE-2025-35052). This vulnerability cannot be exploited by anonymous users.

Impact Analysis

The vulnerability allows an authenticated attacker to read arbitrary files on the system with the privileges of the NIX service, which is typically 'NT AUTHORITY\NetworkService'. This could lead to unauthorized disclosure of sensitive information stored on the system, potentially exposing confidential data or system files accessible by that service account.
