MOOS core-moos through 10.4.0 Missing Authentication for MOOSDB Publish, Subscribe and DB_CLEAR

Assigner: VulnCheck
Reserved: 03.09.2026 Published: 03.09.2026 Updated: 03.09.2026

MOOS core-moos through 10.4.0 lacks authentication in the wire protocol, allowing unauthenticated clients to connect with full publish, subscribe, and database clear privileges. Attackers can bypass the compile-time protocol string check and connect with arbitrary client names to execute privileged operations including DB_CLEAR which resets all variables and clears client mail queues.
