Name of the Vulnerable Software and Affected Versions Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02)

Description An unauthenticated OS command injection vulnerability exists in the Shenzhen Aitemi M300 Wi-Fi Repeater. 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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
