Vulnerability details

A command injection vulnerability exists in the D-Link DIR-823G router firmware DIR823G_V1.0.2B05_20181207.bin in the timelycheck and sysconf binaries, which process the /var/system/linux_vlan_reinit file. The vulnerability occurs because content read from this file is only partially validated for a prefix and…

Why these techniques?

The vulnerability is a command injection in Linux binaries on router firmware, allowing arbitrary Unix shell execution via system() after insufficient validation of a writable file's content (T1059.004). This facilitates privilege escalation from file write capability to command execution in likely elevated context (T1068).
