Deeper analysis
Tenda AC9 firmware version 15.03.05.14 contains a command injection vulnerability in its Telnet implementation, tracked as CVE-2025-45042. The flaw is rooted in improper handling of user-supplied input (CWE-77 and CWE-78), allowing arbitrary command execution on the device. It carries a CVSS 3.1 score of 9.8, reflecting network-accessible exploitation without authentication or user interaction.
An unauthenticated attacker with network reachability to the router can supply crafted input through the Telnet interface to execute operating-system commands. Successful exploitation grants full control over the device, enabling arbitrary code execution with impacts to confidentiality, integrity, and availability.
Public references consist of a technical write-up and proof-of-concept on GitHub that demonstrate the injection vector; no vendor advisory or firmware patch is referenced in the available materials. The EPSS score has remained steady at 0.1648 with no material increase observed since disclosure.
