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.

Executive Summary

This vulnerability exists in Newforma Info Exchange (NIX), where the system accepts serialized .NET data via the '/remoteweb/remote.rem' endpoint. This allows a remote, unauthenticated attacker to execute arbitrary code with 'NT AUTHORITY\NetworkService' privileges. Because this endpoint is used by Newforma Project Center Server (NPCS), a compromised NIX system can be leveraged to attack an associated NPCS system. The vulnerability arises from the unsafe deserialization of data, enabling remote code execution without authentication.

Impact Analysis

The vulnerability can lead to remote code execution on the affected system with elevated privileges ('NT AUTHORITY\NetworkService'), allowing an attacker to take control of the system remotely without authentication. This can result in unauthorized access, data compromise, disruption of services, and potentially using the compromised system as a pivot point to attack associated systems like Newforma Project Center Server (NPCS).

Detection Guidance

Detection can focus on monitoring access to the vulnerable endpoint '/remoteweb/remote.rem' on the Newforma Info Exchange (NIX) system. Network or web server logs should be checked for any requests to this endpoint, especially from unauthenticated sources. Commands to detect such activity could include using web server log analysis tools or command-line tools like 'grep' to search logs for '/remoteweb/remote.rem'. For example, on a system with IIS logs, you could run: grep "/remoteweb/remote.rem" C:\inetpub\logs\LogFiles\W3SVC*\*.log. Additionally, network monitoring tools can be configured to alert on HTTP requests targeting this endpoint.

Mitigation Strategies

Immediate mitigation involves restricting network access to the '/remoteweb/remote.rem' endpoint. This can be done by configuring the IIS URL Rewrite Module to block or restrict requests to this endpoint. Using the URL Rewrite Module, administrators can create rules to deny or redirect requests targeting '/remoteweb/remote.rem', effectively preventing exploitation. Additional network-level controls such as firewall rules to block external access to this endpoint can also be applied. [2]
