CVE-2022-42982 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

BKG Professional NtripCaster 2.0.39 allows querying information over the UDP protocol without authentication. The NTRIP sourcetable is typically quite long (tens of kBs) and can be requested with a packet of only 30 bytes. This presents a vector that can be used for UDP amplification attacks. Normally, only authenticated streaming data will be provided over UDP and not the sourcetable.
