CVE-2024-4292Public exploit

Adjacent-network denial of service via crafted DCC packet

Published Apr 27, 2024 · Updated Aug 1, 2024

BASrouter BACnet BASRT-B 2.7.2 allows remote attackers on an adjacent network to interrupt routing via a crafted DCC packet. The Device-Communication-Control Service processes the published byte sequence, but the vendor has not disclosed the faulty operation that causes denial of service. Reachability requires BACnet adjacency; the public record establishes availability loss only and does not identify whether the device hangs, crashes, or reboots.
