This signature detects attempts to exploit a known vulnerability against MQTT packet parsing functionality of Cesanta Mongoose. A successful attack can result in denial-of-service condition or disclosure of sensitive information.
An issue was discovered in Mongoose before 6.15. The parse_mqtt() function in mg_mqtt.c has a critical heap-based buffer overflow.
