CVE-2022-42982 Information

Description

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.
