## What is CVE-2025-34147?

CVE-2025-34147 is a critical command injection vulnerability in Shenzhen Aitemi E Commerce Co. Ltd. M300 Wi-Fi Repeater, published on 4 Aug 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An unauthenticated OS command injection vulnerability exists in the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02). When configuring the device in Extender mode via its captive portal, the extap2g SSID field is inserted unescaped into a reboot-time shell script. This allows remote attackers within Wi-Fi range to inject arbitrary shell commands that execute as root during device reboot, leading to full system compromise.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)
