Unauthenticated Command Injection in WIFISKY 7-layer Flow Control Router confirm.php

A successful exploit allows an unauthenticated remote attacker to execute arbitrary operating system commands on the affected router. This can result in full compromise of the device, including unauthorized administrative control, modification of configuration, deployment of malware or botnet payloads, interception or manipulation of network traffic, establishment of persistence, and use of the device as a pivot point for further attacks into the local network. Given that the target is a network edge device, compromise may also enable service disruption and broad visibility into routed traffic.

Until a patch is available and deployed, restrict access to the affected web management interface so it is not reachable from the public Internet or untrusted networks. Enforce network-layer controls such as firewall ACLs, VPN-only administrative access, IP allowlisting, and segmentation of management interfaces. Disable remote administration if not operationally required. Monitor HTTP requests to confirm.php, especially GET requests containing suspicious values in the t parameter, and review device logs and network telemetry for indicators of command injection or post-exploitation activity. If compromise is suspected, isolate the device, rotate credentials, review configuration integrity, and reimage or replace the device with trusted firmware.

Apply the vendor-provided security update or fixed firmware for WIFISKY 7-layer Flow Control Router if available. If an official patch has not yet been released or cannot be validated from the available information, upgrade to the latest firmware version provided by the vendor and confirm whether it addresses CVE-2025-34044. The vulnerable confirm.php handling of the t parameter should be corrected by implementing strict server-side input validation, rejecting metacharacters and command separators, and avoiding direct use of untrusted input in shell command execution. If custom maintenance is possible, replace shell invocation with safe parameterized APIs that do not invoke a command interpreter.
