CVE-2025-69542Public exploitNetwork attack vector

Root command execution via unsanitized DHCP hostname

Published Jan 9, 2026 · Updated Jan 9, 2026

Command injection in D-Link DIR895LA1 firmware 102b07 allows remote attackers to execute arbitrary commands as root via DHCP renewal. The DHCP REQUEST handler copies Option 12 into a NEW_DEVICE command string and passes it to system() without neutralizing shell metacharacters. Reachability requires renewal of an existing lease; injected commands can read or alter router data and configuration.
