Newforma Project Center Server (NPCS) .NET unauthenticated deserialization

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) .NET unauthenticated deserialization

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 Info Exchange (NIX) default anonymous access

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) forced NTLMv2 authentication via /UserWeb/Common/MarkupServices.ashx

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) forced NTLMv2 authentication via /NPCSRemoteWeb/LegacyIntegrationServices.asmx

Newforma Info Exchange (NIX) '/NPCSRemoteWeb/LegacyIntegrationServices.asmx' 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 user-configured NIX service account.

Newforma Info Exchange (NIX) open URL redirect via /DownloadWeb/hyperlinkredirect.aspx

Newforma Info Exchange (NIX) '/DownloadWeb/hyperlinkredirect.aspx' provides an unauthenticated URL redirect via the 'nhl' parameter.

Newforma Info Exchange (NIX) stored XSS via SVG file upload

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) arbitrary file read and delete

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.

Newforma Info Exchange (NIX) shared hard-coded secret key

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) insufficiently protected credentials

Newforma Info Exchange (NIX) stores credentials used to configure NPCS in 'HKLM\Software\WOW6432Node\Newforma\<version>\Credentials'. The credentials are encrypted but the encryption key is stored in the same registry location. Authenticated users can access both the credentials and the encryption key. If these are Active Directory credentials, an attacker may be able to gain access to additional systems and resources.

Newforma Info Exchange (NIX) insecure file upload

Newforma Info Exchange (NIX) '/UserWeb/Common/UploadBlueimp.ashx' allows an authenticated attacker to upload an arbitrary file to any location writable by the NIX application. An attacker can upload and run a web shell or other content executable by the web server. An attacker can also delete directories. 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.

Newforma Info Exchange (NIX) limited file read

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) forced NTLMv2 authentication via /RemoteWeb/IntegrationServices.ashx

Newforma Info Exchange (NIX) '/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 Project Center Server through 2023.3.0.32259 allows remote code execution because .NET Remoting is exposed.
