CVE-2025-55423

CRITICAL

ipTIME Router Firmware - OS Command Injection via UPnP Relay controlURL Parameter

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2025-55423. PoCs published by logis11.

AI-analyzed exploit summary This repository contains a functional proof-of-concept exploit for CVE-2025-55423, demonstrating a command injection vulnerability in the ipTIME router firmware. The exploit chain includes SSDP and HTTP servers to simulate a malicious UPnP device, along with a C-based harness to trigger the RCE in an emulated environment.

Description

A command injection vulnerability exists in the upnp_relay() function in multiple ipTIME router models because the controlURL value used to pass port-forwarding information to an upper router is passed to system() without proper validation or sanitization, allowing OS command injection.
