What is CVE-2025-35050?

CVE-2025-35050 is a critical unsafe deserialization vulnerability in Newforma Project Center, published on 9 Oct 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

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.
