Severity CVSS v4.0:

CRITICAL

Type:

CWE-306 Missing Authentication for Critical Function

Publication date:

Description

Newforma Info Exchange (NIX) accepts serialized .NET data via the &#39;/remoteweb/remote.rem&#39; endpoint, allowing a remote, unauthenticated attacker to execute arbitrary code with &#39;NT AUTHORITY\NetworkService&#39; 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 &#39;/remoteweb/remote.rem&#39; endpoint, for example using the IIS URL Rewrite Module.
