Summary

PTC Windchill PDMLink and FlexPLM contain a vulnerability (CWE-94) that allows unauthenticated remote code execution. An attacker can exploit this vulnerability over the network to execute arbitrary commands on affected systems. The vulnerability affects Windchill PDMLink versions 11.0_M030 through 13.1.3.0 and FlexPLM versions 11.0_M030 through 13.0.3.0. PTC is actively developing vendor patches; in the meantime, HTTP server configuration workarounds must be applied immediately to all deployments, with particular urgency for publicly accessible systems.

What this means
What could happen
An attacker could execute arbitrary commands on Windchill or FlexPLM servers over the network without authentication, potentially allowing them to modify product lifecycle data, steal design files, or disrupt design and engineering workflows that feed into manufacturing and production systems.
Who's at risk
Organizations using PTC Windchill PDMLink or FlexPLM for product lifecycle management, particularly those with publicly accessible systems. This includes manufacturers, engineering firms, and enterprises managing product design, CAD files, bill of materials, and engineering change orders that feed into production planning and manufacturing execution systems.
How it could be exploited
An attacker can send a specially crafted request over the network to a publicly accessible Windchill or FlexPLM server. The vulnerability allows remote code execution without needing valid credentials or user interaction. The attacker gains command execution on the server, which can be leveraged to access or modify critical product data and engineering files.
Prerequisites
  • Network access to the Windchill or FlexPLM web server port (typically HTTP/HTTPS)
  • Windchill PDMLink version 11.0_M030 through 13.1.3.0, or FlexPLM version 11.0_M030 through 13.0.3.0
  • No valid credentials or authentication required
