CVE-2024-6143 is a buffer overflow vulnerability in the HTTP server of Actiontec WCB6200Q routers, allowing network-adjacent attackers to execute arbitrary code without authentication due to insufficient validation of user-supplied data length. This vulnerability carries a high CVSS score of 8.8, indicating a critical risk with an adjacent attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While no public exploits, Metasploit modules, or KEV entries exist, and community discussion is minimal, the potential for unauthenticated remote code execution makes it a significant concern for affected devices.
