CVE-2025-35055

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.

Newforma Info Exchange (NIX) before version 2023.1 by default allows anonymous authentication, which allows an unauthenticated attacker to exploit additional vulnerabilities that require authentication.

Newforma Info Exchange (NIX) allows a remote, unauthenticated attacker to cause NIX to make an SMB connection to an attacker-controlled system. The attacker can capture the NTLMv2 hash of the NIX service account.

Newforma Info Exchange (NIX) provides a 'Send a File Transfer' feature that allows a remote, authenticated attacker to upload SVG files that contain JavaScript or other content that may be executed or rendered by a web browser using a mobile user agent.

Newforma Info Exchange (NIX) '/DownloadWeb/hyperlinkredirect.aspx' provides an unauthenticated URL redirect via the 'nhl' parameter. An attacker can use this parameter to redirect users to an arbitrary site.

Newforma Info Exchange (NIX) '/UserWeb/Common/MarkupServices.ashx' allows a remote, unauthenticated attacker to cause NIX to make an SMB connection to an attacker-controlled system. The attacker can capture the NTLMv2 hash of the customer-configured NIX service account.

Newforma Info Exchange (NIX) in '/RemoteWeb/IntegrationServices.ashx' allows a remote, unauthenticated attacker to cause NIX to make an SMB connection to an attacker-controlled system. The attacker can capture the NTLMv2 hash of the NIX service account.

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 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 versions 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 vulnerability.

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.
