| Título | D-Link DIR895LA1_102b07 A1_102b07 Command Injection |
|---|
| Descripción | A command injection vulnerability exists in the `udhcpcd` DHCP server of D-Link DIR-895L. The issue is located in the `sendACK()` path, where the server reads a client-controlled DHCP hostname from `Option 12`, concatenates it into a shell command for the TR-069 host helper, and executes the resulting string with `system()`.
Because the vulnerable path is reachable by an unauthenticated DHCP client on the local network, a remote attacker on the LAN can execute arbitrary commands as root by sending a crafted DHCP request containing a malicious hostname. |
