CVE-2025-35050

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) '/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) in '/UserWeb/Common/UploadBlueimp.ashx' allows an authenticated attacker to upload an arbitrary file to any writable location. An attacker can upload and run a web shell or other executable content, and also delete directories. In versions before 2023.1, anonymous access is enabled by default, allowing unauthenticated attackers to exploit this.

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.
