Detailsinfo

A vulnerability was found in Shenzhen Aitemi M300 Wi-Fi Repeater MT02. It has been rated as critical. This issue affects an unknown code. The manipulation of the argument extap2g SSID with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.
