Medium (5.3) in dproxy-nexgen project dproxy-nexgen. EPSS 1.0% chance of exploitation in the next 30 days.

dproxy-nexgen (aka dproxy nexgen) uses a static UDP source port (selected randomly only at boot time) in upstream queries sent to DNS resolvers. This allows DNS cache poisoning because there is not enough entropy to prevent traffic injection attacks.
