CVE-2023-1864Network attack vector

Remote file read via path traversal

Published Jun 7, 2023 · Updated Jan 6, 2025

Path traversal in FANUC ROBOGUIDE-HandlingPRO 9 Rev.ZD and earlier allows remote attackers to read host files via crafted network packets. Public advisories do not identify the packet field, file-handling routine, or path-validation error that permits traversal. Exploitation requires knowledge of specific ROBOGUIDE user data, such as workcell configuration details, and exposes files accessible to the affected process.
