CVE-2025-4341Network attack vector

Authenticated command execution via crafted request headers

Published May 6, 2025 · Updated May 6, 2025

Command injection in D-Link DIR-880L 104WWb01 allows remote authenticated users to execute commands through crafted request headers. The sub_16570 function in /htdocs/ssdpcgi fails to neutralize HTTP_ST, REMOTE_ADDR, REMOTE_PORT, or SERVER_ID values before command processing. Low-privileged access is required, and successful exploitation executes commands on the router without user interaction.
