CVE-2025-55112Network attack vector

Traffic disclosure via hard-coded Blowfish key

Published Sep 16, 2025 · Updated Sep 16, 2025

Hard-coded cryptographic keys in BMC Control-M/Agent 9.0.18 through 9.0.20 allow attackers to decrypt Agent-Server traffic. Blowfish keys embedded in the Agent binary files encrypt the channel with a shared, recoverable secret rather than a deployment-specific key. Exposure requires the non-default Blowfish configuration plus access to both the network traffic and the embedded key, and permits disclosure of protected traffic.
