Summary

FANUC ROBOGUIDE simulation platform versions 9.40083.00.05 (Rev T) and earlier contain multiple vulnerabilities that could allow denial of service, remote code execution, or unauthorized privilege escalation. The vulnerabilities stem from improper access control (CWE-732, CWE-284), path traversal (CWE-22), XML external entity processing (CWE-611), and resource exhaustion (CWE-400). Successful exploitation requires network access to the workstation and user interaction, such as opening a malicious file. An attacker could execute code with the privileges of the ROBOGUIDE application, potentially altering robot programs or disrupting engineering work.

What this means
What could happen
An attacker could deny service to the ROBOGUIDE simulation platform, execute arbitrary code on the engineering workstation running it, or escalate privileges to gain unauthorized control of robot programming and simulation functions.
Who's at risk
This affects manufacturing plants using FANUC robots for production, assembly, or material handling. Specifically, it impacts engineering teams and automation technicians who use ROBOGUIDE to design and simulate robot programs before deployment to production floor controllers. Any plant that develops or maintains custom FANUC robot automation is at risk.
How it could be exploited
An attacker would need to reach the workstation running ROBOGUIDE over the network and trick an engineer to open a malicious file or interact with a specially crafted input (the advisory indicates user interaction is required). Once executed, the attacker gains the ability to run commands with the privileges of the ROBOGUIDE application, potentially affecting robot behavior or plant automation design work.
Prerequisites
  • Network access to the engineering workstation running ROBOGUIDE
  • User interaction required (likely opening a malicious file or project)
  • ROBOGUIDE version 9.40083.00.05 (Rev T) or earlier installed
