A weakness has been identified in D-Link DIR-823X 240126/240802/250416. The impacted element is the function sub_412E7C of the file /usr/sbin/goahead of the component Environment Variable Handler. This manipulation of the argument terminal_addr/server_ip/server_port causes command injection. The attack can be initiated remotely. The exploit has been made available to the public and could be exploited.
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
