CVE-2024-25136Network attack vector

Unauthenticated service interruption via unsanitized URL path

Published Mar 26, 2024 · Updated Aug 8, 2024

Path traversal in AutomationDirect C-MORE EA9 HMI 6.77 and earlier allows remote attackers to interrupt service via a crafted URL. A web-server function accepts relative path components in a URL without sanitizing them before resolving the requested resource. The web server must be enabled and network reachable; exploitation requires no authentication or user interaction and affects availability only.
