CVE-2020-12001Network attack vector

Unauthenticated code execution via unchecked file path

Published Jun 15, 2020 · Updated Aug 4, 2024

Path traversal in Rockwell Automation FactoryTalk Linx 6.00, 6.10, and 6.11 allows remote attackers to execute arbitrary code. The CopyRenameProject parameter in hmi_isapi.dll accepts a user-supplied path for file operations without validating that it stays within an authorized directory. An unauthenticated network request to the exposed service is sufficient to overwrite files and run code in the service process context.
