AI-suggested
- Immediately segment networks to isolate Shenzhen Aitemi M300 devices from sensitive internal networks, limiting attacker pivot opportunities.
- Disable Extender mode on the M300 devices if not strictly necessary, as the vulnerability is triggered only in this mode.
- Restrict physical and Wi-Fi access to trusted users and devices; implement strong Wi-Fi authentication and monitoring to detect rogue access points or suspicious SSID changes.
- Monitor device logs and network traffic for unusual reboot events or unexpected shell command executions.
- Employ wireless intrusion detection/prevention systems (WIDS/WIPS) to detect malicious SSID broadcasts or injection attempts.
- Engage with Shenzhen Aitemi for firmware updates or patches and apply them promptly once available.
- Consider replacing vulnerable devices with alternatives that have stronger security postures if immediate patching is not possible.
- Educate IT and security teams about the vulnerability and signs of exploitation to enable rapid incident response.
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.
