## Technical details

A command injection vulnerability exists in the sendACK function of udhcpcd/serverpacket.c in D-Link DIR-895L firmware version A1_102b07. The vulnerable component is the DHCP server (udhcpcd), which processes client requests without properly sanitizing the Hostname argument. An attacker can send a specially crafted DHCP request containing shell metacharacters in the Hostname field to execute arbitrary commands on the router with system privileges. The attack requires network access to the router's DHCP service and can be performed remotely without authentication. A patch or firmware update may be available from D-Link.
