CVE-2025-31362Network attack vector

Credential disclosure via shared robot-file encryption key

Published Apr 11, 2025 · Updated Apr 11, 2025

Hard-coded key use in OPEN, Inc. BizRobo! all versions allows remote attackers to recover credentials from obtained robot files. The platform encrypts credential information embedded in every robot file with the same single cryptographic key rather than a per-deployment secret. Exploitation requires access to both a robot file and the shared key; the documented consequence is credential disclosure, not data modification or service interruption.
