9.1 (CRITICAL)

DescriptionCVE.org

The GoAhead web server on MeiG Smart FORGE_SLT711 devices (firmware MDM9607.LE.1.0-00110-STD.PROD-1) allows unauthenticated OS command injection via the /action/SetRemoteAccessCfg endpoint.

AnalysisAI

Unauthenticated remote OS command injection in MeiG Smart FORGE_SLT711 cellular gateway firmware MDM9607.LE.1.0-00110-STD.PROD-1 allows attackers to execute arbitrary system commands via the /action/SetRemoteAccessCfg endpoint in the GoAhead web server. CVSS 9.1 reflects critical impact with network-accessible attack vector requiring no authentication or user interaction. GitHub repository suggests publicly available exploit code exists (CVE-2026-36356), significantly lowering exploitation barrier for attackers targeting industrial IoT and cellular gateway deployments.

Technical ContextAI

This vulnerability exploits CWE-78 (OS Command Injection) in the GoAhead embedded web server, a lightweight HTTP server commonly deployed in IoT and embedded devices. The /action/SetRemoteAccessCfg endpoint fails to properly sanitize user-supplied input before passing it to system shell commands. The affected MeiG FORGE_SLT711 is a 4G LTE industrial cellular gateway built on Qualcomm's MDM9607 chipset platform, running firmware version MDM9607.LE.1.0-00110-STD.PROD-1. GoAhead's architecture typically runs with elevated system privileges to manage device configuration, meaning injected commands likely execute with root or administrative permissions. The vulnerability exists in the remote access configuration interface, which would normally handle VPN, SSH, or remote management settings-functionality that by design interacts with system-level services.

RemediationAI

Contact MeiG Smart directly through official support channels to request patched firmware for FORGE_SLT711 devices, as no vendor-released patch version is confirmed in available data. No vendor advisory is published at forgeslt711.com or meig.com references provided. Until patched firmware is available, implement immediate network-layer compensating controls: (1) Block external access to the GoAhead web interface (typically TCP ports 80/443) using firewall rules-allow management only from trusted internal networks or VPN connections, with side effect of preventing remote administration convenience. (2) Deploy network segmentation to isolate FORGE_SLT711 gateways into dedicated VLAN with strict ingress/egress filtering-limits lateral movement if compromised but adds infrastructure complexity. (3) Implement application-layer firewall or reverse proxy with input validation to filter requests to /action/SetRemoteAccessCfg endpoint-requires custom WAF rules and ongoing maintenance. (4) Monitor device logs and network traffic for suspicious POST requests containing shell metacharacters (semicolons, pipes, backticks) to /action/ paths-provides detection but not prevention. Given the unauthenticated nature and POC availability, network isolation is the only reliable mitigation until vendor patch is deployed.
