A buffer overflow vulnerability exists in the TOTOLINK A950RG Router firmware version V5.9c.4592_B20191022_ALL in the global.so binary. The vulnerability arises from the getSaveConfig function copying user-supplied http_host parameter data into a fixed-size stack buffer without length checks. This flaw allows an unauthenticated remote attacker to send a crafted HTTP request to the router's web interface and potentially execute arbitrary code.
