CVE-2024-48077 Details
Description
NanoMQ v0.22.7 is vulnerable to Denial of Service (DoS) due to improper resource throttling. A crafted sequence of requests causes the recv-q queue to saturate, leading to the rapid exhaustion of system file descriptors (FDs). This exhaustion triggers a process crash, rendering the broker unable to provide services.
A denial-of-service vulnerability has been identified in NanoMQ version 0.22.7. This issue allows attackers to send a large number of crafted MQTT packets to the NanoMQ broker, causing the 'recv-q' queue to fill up rapidly. This accumulation leads to a deadlock, exhausting file descriptor resources and causing the broker to become unresponsive, unable to provide normal services.
