CVE-2025-35050

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 AUTHORITYNetworkService’ 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.
