The exploit has been made available to the public and could be used for attacks.
A command injection vulnerability exists in the D-Link DIR-823G router firmware DIR823GV1.0.2B0520181207.bin in the timelycheck and sysconf binaries, which process the /tmp/newqos.rule configuration file. The vulnerability occurs because parsed fields from the configuration file are concatenated into command strings and executed via system() without any sanitization. An attacker with write access to /tmp/newqos.rule can execute arbitrary commands on the device.
A command injection vulnerability exists in the D-Link DIR-823G router firmware DIR823GV1.0.2B0520181207.bin in the timelycheck and sysconf binaries, which process the /var/system/linuxvlanreinit file. The vulnerability occurs because content read from this file is only partially validated for a prefix and then formatted using vsnprintf() before being executed with system(), allowing an attacker with write access to /var/system/linuxvlanreinit to execute arbitrary commands on the device.

An issue was discovered on D-Link DIR-823G devices with firmware through 1.02B03. A command Injection vulnerability allows attackers to execute arbitrary OS commands via shell metacharacters in a crafted /HNAP1 request. This occurs when the GetNetworkTomographyResult function calls the system function with an untrusted input parameter named Address. Consequently, an attacker can execute any command remotely when they control this input.
An issue was discovered on D-Link DIR-823G devices with firmware through 1.02B03. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 request. This occurs when any HNAP API function triggers a call to the system function with untrusted input from the request body, such as a body of ' /bin/telnetd' for the GetDeviceSettingsset API function. Consequently, an attacker can execute any command remotely when they control this input.
