Kerentanan OWASP Top Ten 2017 Category A9 - Using Components with Known Vulnerabilities. Skor CVSS 3.1 7.5 (High) menurut redhat.com.
A flaw was found in Netty's MqttDecoder. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted MQTT CONNECT packet. The decoder fails to properly validate the 'Properties Length' against the 'Remaining Length', allowing an attacker to bypass size limits. This leads to excessive memory and CPU consumption, resulting in a denial of service (DoS) due to an OutOfMemoryError.
