Name of the Vulnerable Software and Affected Versions Eclipse Mosquitto version 1.4.14
Description The issue allows a user to shut down the Mosquitto server by filling the RAM memory with numerous connections that have large payloads. This can be achieved without authentication during the connection phase of the MQTT protocol.
Recommendations For Eclipse Mosquitto version 1.4.14, consider restricting the number of connections or limiting the payload size to prevent excessive memory usage until a patch is available. As a temporary workaround, implement authentication for the connection phase to minimize the risk of exploitation.
