| Title | D-Link DIR-823X 250416 OS Command Injection |
|---|
| Description | A critical Command Injection vulnerability exists in the D-Link DIR-823X firmware. The vulnerability is located in the function sub_41E2A0, which is associated with the /goform/set_mode path.
The application retrieves network configuration parameters lan_ipaddr, lan_netmask, and lan_gateway from the user-controlled input (a1) via sub_4108AC. When the lan_gateway (variable s) is provided, the application attempts to update the system's DHCP configuration using the sub_412E7C function, which executes system shell commands. |
