Description

MOOS core-moos through 10.4.0 contains a remote process termination vulnerability in the SuicidalSleeper component that uses a hard-coded passphrase for multicast command authorization. Any multicast-reachable peer can enumerate MOOS processes and send termination commands to trigger process shutdown by exploiting the default multicast group and port with the known passphrase.
