CVE-2018-19417 is a critical remote code execution vulnerability affecting the MQTT server in Contiki-NG versions prior to 4.2. It stems from a missing length check in the parse_publish_vhdr() function, allowing a stack-smashing attack via oversized MQTT PUBLISH messages. This vulnerability carries a CVSS score of 10.0 (Critical) due to its network-based attack vector, low complexity, and potential for complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, the high FAUCET Risk Score of 86/100 indicates its severe potential.
