Описание
A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the prog.cgi and librcm.so binaries. The sub_4455BC function in prog.cgi stores user-supplied SetDMZSettings/IPAddress values in NVRAM via nvram_safe_set("dmz_ipaddr", ...). These values are later retrieved in the DMZ_run function of librcm.so using nvram_safe_get and concatenated into iptables shell commands executed via twsystem() without any sanitization. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.

A command injection vulnerability exists in the D-Link DIR-882 Router firmware DIR882A1_FW102B02 within the `prog.cgi` and `librcm.so` binaries. The `sub_4455BC` function in `prog.cgi` stores user-supplied `SetDMZSettings/IPAddress` values in NVRAM via `nvram_safe_set("dmz_ipaddr", ...)`. These values are later retrieved in the `DMZ_run` function of `librcm.so` using `nvram_safe_get` and concatenated into `iptables` shell commands executed via `twsystem()` without any sanitization. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary commands on the device through specially crafted HTTP requests to the router's web interface.
