CVE-2025-45042Public exploitNetwork attack vector

Remote command execution via Telnet route input

Published May 5, 2025 · Updated May 5, 2025

OS command injection in the Telnet function of Tenda AC9 15.03.05.14 allows remote attackers to execute commands via an HTTP request. The published analysis identifies shell-metacharacter handling in the /goform/telnet POST handler but does not disclose the vulnerable parameter or command-building code. Its proof of concept supplies an administrative cookie, while the published CVSS assessment treats exploitation as unauthenticated, leaving the practical authentication gate unresolved.
