    Published: 3 Sept 2026Last Modified: 10 Sept 2026

    Summary: MOOS core-moos through 10.4.0 MOOSDB Denial of Service via Unbounded Packet Allocation

    Details: MOOS core-moos through 10.4.0 fails to validate packet length declarations in CMOOSCommPkt::OnBytesWritten(), allowing unauthenticated attackers to trigger unbounded buffer allocation by sending crafted wire packets. Attackers can send packets with large declared lengths to exhaust server memory and cause denial of service before client authentication completes.
