What to do
AI-suggested
Until a fix is available, restrict write access to the /tmp/new_qos.rule file and monitor for unauthorized modifications to mitigate exploitation risk.
Description
A command injection vulnerability exists in the D-Link DIR-823G router firmware version DIR823G_V1.0.2B05_20181207.bin. The flaw is in the timelycheck and sysconf binaries that process the /tmp/new_qos.rule configuration file without sanitizing input before executing commands. An attacker with write access to this file can execute arbitrary commands on the device.
