A buffer overflow vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the global.so binary. The getSaveConfig function retrieves the http_host parameter from user input via websGetVar and copies it into a fixed-size stack buffer (v13) using strcpy() without performing any length checks. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted HTTP request to the router's web interface, potentially leading to arbitrary code execution.
