CVE-2017-2921 is a critical memory corruption vulnerability affecting Cesanta Mongoose 6.8's Websocket protocol implementation. A specially crafted websocket packet can trigger an integer overflow, leading to a heap buffer overflow. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low complexity, and potential for denial of service and remote code execution. While no active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB) has been identified, and community discussion is minimal, the high FAUCET Risk Score of 81/100 indicates its significant potential impact.
