CVE-2025-29519Public exploitNetwork attack vector

Unauthenticated command execution via crafted EXE parameter

Published Aug 25, 2025 · Updated Aug 26, 2025

Command injection in D-Link DSL-7740C firmware DSL7740C.V6.TR069.20211230 allows remote attackers to execute commands via a GET request. The router's web interface incorporates the EXE query parameter into command processing without neutralizing command syntax. No authentication or user interaction is required; successful exploitation alters command execution on the device, with no reported disclosure or service interruption.
