CVE-2026-3485Public exploitNetwork attack vector

Unauthenticated command execution via crafted SSDP ST

Published Mar 3, 2026 · Updated Mar 3, 2026

OS command injection in D-Link DIR-868L 110b03 allows remote attackers to execute commands through a crafted SSDP ST argument. The SSDP Service function sub_1BF84 processes the attacker-controlled ST value without neutralizing operating-system command syntax. No authentication or user interaction is required, and successful exploitation executes commands in the router firmware context.
