Insufficient Control of Network Message Volume (Network Amplification)
CWE-406
The product does not sufficiently monitor or control transmitted network traffic volume, so that an actor can cause the product to transmit more traffic than should be allowed for that actor.
In the absence of a policy to restrict asymmetric resource consumption, the application or system cannot distinguish between legitimate transmissions and traffic intended to serve as an amplifying attack on target systems. Systems can often be configured to restrict the amount of traffic sent out on behalf of a client, based on the client's origin or access level. This is usually defined in a resource allocation policy. In the absence of a mechanism to keep track of transmissions, the system or application can be easily abused to transmit asymmetrically greater traffic than the request or client should be permitted to.
We track 6 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 7.9. 1 has been exploited in real attacks.
How this weakness is prevented
- Architecture and Design: An application must make network resources available to a client commensurate with the client's access level.
- Policy: Define a clear policy for network resource allocation and consumption.
- Implementation: An application must, at all times, keep track of network resources and meter their usage appropriately.

QTINeon: Uncontrolled Resource Consumption
QTI Neon is a minimal, game-agnostic, relay-based UDP multiplayer protocol library. In version 1.0.0, the relay's handleReconnectRequest forwards RECONNECT_REQUEST packets to the host without bounding them, so an unauthenticated client can drive relay-to-host

dns_server: Insufficient Control of Network Message Volume (Network Amplification)
Technitium 11.5.3 allows remote attackers to cause a denial of service (bandwidth amplification) because the DNSBomb manipulation causes accumulation of low-rate DNS queries such that there is a large-sized response in a burst of traffic.

dns_server: Insufficient Control of Network Message Volume (Network Amplification)
An issue was discovered in Technitium through 11.0.2. It enables attackers to launch amplification attacks (3 times more than other "golden model" software like BIND) and cause potential DoS.

dns_server: Insufficient Control of Network Message Volume (Network Amplification)
An issue was discovered in Technitium through 11.0.2. The forwarding mode enables attackers to create a query loop using Technitium resolvers, launching amplification attacks and causing potential DoS.

MQ: Insufficient Control of Network Message Volume (Network Amplification)
IBM MQ 9.2 LTS, 9.3 LTS, and 9.3 CD Internet Pass-Thru could allow a remote user to cause a denial of service by sending HTTP requests that would consume all available resources. IBM X-Force ID: 281278.

Palo Alto Networks PAN-OS Reflected Amplification Denial-of-Service Exploited
A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. The DoS attack would appear to originate from a Palo Alto Networks PA-Series (hardware), VM-Series (vir
