## Technical details

An OS command injection vulnerability exists in the 'formWifiApScan' function (offset 0x4b1914) within the '/bin/httpd' binary of Tenda AC6 V2.0 firmware V15.03.06.23. The vulnerability is rooted in the improper neutralization of the 'wl2g.public.country' and 'wl5g.public.country' parameters. These values are retrieved via 'websGetVar()' and subsequently passed to 'doSystemCmd()'—which internally calls 'system()'—without any input sanitization. A remote attacker with authenticated access (PR:L) can exploit this by sending a specially crafted POST request to '/goform/WifiApScan' to execute arbitrary shell commands. A public exploit (PoC) is available.
