Vulnerability Spotlight: Multiple Vulnerabilities in Cesanta Mongoose Server
Summary: Cisco Talos disclosed several vulnerabilities in Cesanta Mongoose, a lightweight networking library implementing HTTP, MQTT, MDNS and other protocols that runs on virtually all popular IoT platforms. All the vulnerabilities are fixed in version 6.10 of the library, and Talos says they may allow attackers to take over vulnerable implementations and control individual devices as well as the associated servers running it.
Bottom line: Mongoose is built into many internet-connected embedded devices, so an unpatched library leaves attackers a path to take control of the device itself and the servers behind it - and the fix only reaches you when affected device vendors ship it.
