Description
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.
