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.

Newforma Info Exchange (NIX) accepts serialized .NET data via the '/remoteweb/remote.rem' endpoint, allowing a remote, unauthenticated attacker to execute arbitrary code with 'NT AUTHORITY\NetworkService' privileges. The vulnerable endpoint is used by Newforma Project Center Server (NPCS), so a compromised NIX system can be used to attack an associated NPCS system. To mitigate this vulnerability, restrict network access to the '/remoteweb/remote.rem' endpoint, for example using the IIS URL Rewrite Module. Newforma Project Center Server (NPCS) accepts serialized .NET data via the '/ProjectCenter.rem' endpoint on 9003/tcp, allowing a remote, unauthenticated attacker to execute arbitrary code with 'NT AUTHORITY\NetworkService' privileges. According to the recommended architecture, the vulnerable NPCS endpoint is only accessible on an internal network. To mitigate this vulnerability, restrict network access to NPCS. Newforma Info Exchange (NIX) uses a hard-coded key to encrypt certain query parameters. Some encrypted parameter values can specify paths to download files, potentially bypassing authentication and authorization, for example, the 'qs' parameter used in '/DownloadWeb/download.aspx'. This key is shared across NIX installations. NIX 2023.3 and 2024.1 limit the use of hard-coded keys. Newforma Info Exchange (NIX) accepts requests to '/UserWeb/Common/MarkupServices.ashx' specifying the 'DownloadExportedPDF' command that allow an authenticated user to read and delete arbit…
