CVE-2025-14659 Details
Description
A vulnerability was detected in D-Link DIR-860LB1 and DIR-868LB1 203b01/203b03. Affected is an unknown function of the component DHCP Daemon. The manipulation of the argument Hostname results in command injection. It is possible to launch the attack remotely. The exploit is now public and may be used.
A command injection vulnerability has been identified in the DHCP daemon of the D-Link DIR-860LB1 and DIR-868LB1 routers, specifically in versions 203b01 and 203b03. The issue arises because the DHCP hostname parameter is improperly sanitized before being used in system commands. This flaw allows remote attackers to execute arbitrary commands with root privileges by sending malicious hostname data during the DHCP lease renewal process.
