CVE-2026-85451: Use of Hard-coded Credentials in themoos core-moos
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.

Technical Analysis
The vulnerability in MOOS core-moos through version 10.4.0 involves the SuicidalSleeper component using a hard-coded passphrase for multicast command authorization. This design flaw enables any attacker on the multicast network to enumerate running MOOS processes and send commands to terminate them remotely by exploiting the default multicast group and port with the known passphrase. The vulnerability does not require privileges or user interaction and has low attack complexity but results in high impact on availability due to remote process termination.
Potential Impact
An attacker with multicast network access can remotely terminate MOOS processes by sending authorized multicast commands using the hard-coded passphrase. This results in denial of service through process shutdown, impacting system availability. No privileges or user interaction are required for exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict multicast network access to trusted hosts only to reduce exposure.
