    CVE-2020-36872 (GCVE-0-2020-36872)

    Vulnerability from cvelistv5 – Published: 2025-11-26 22:13 – Updated: 2026-05-14 02:06

    Title
    BACnet Test Server 1.01 Malformed BVLC Length DoS
    Summary
    BACnet Test Server versions up to and including 1.01 contains a remote denial of service vulnerability in its BACnet/IP BVLC packet handling. The server fails to properly validate the BVLC Length field in incoming UDP BVLC frames on the default BACnet port (47808/udp). A remote unauthenticated attacker can send a malformed BVLC Length value to trigger an access violation and crash the application, resulting in a denial of service.
