CVE-2022-3090Network attack vector

Credential-hash disclosure via crafted file path

Published Nov 17, 2022 · Updated Apr 16, 2025

Path traversal in Red Lion Controls Crimson 3.0, 3.1, and 3.2 allows remote attackers to obtain Windows user password hashes. Opening a crafted file path makes Crimson contact an arbitrary host for the file, causing Windows to send the current user's password hash to that host. No authentication or user interaction is required; the consequence is credential-hash disclosure rather than direct file-system access.
