Description
A command injection vulnerability affects the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02) during WPA2 configuration. The 'key' parameter is interpreted directly by the system shell, enabling attackers to execute arbitrary commands as root. Exploitation requires no authentication and can be triggered during wireless setup.

Comprehensive Technical Analysis of EUVD-2025-23924
1. Vulnerability Assessment and Severity Evaluation
The EUVD-2025-23924 entry describes a critical command injection vulnerability in the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02). This vulnerability allows attackers to execute arbitrary commands as root during the WPA2 configuration process. The severity of this vulnerability is underscored by its CVSS base score of 9.4, which is classified as critical. The CVSS vector indicates that the attack can be executed with low complexity (AC:L), requires no authentication (PR:N), and can be triggered without user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H), and the scope change is also high (SC:H, SI:H, SA:H).
2. Potential Attack Vectors and Exploitation Methods
The primary attack vector involves exploiting the 'key' parameter during the WPA2 configuration process. An attacker can inject malicious commands into this parameter, which are then executed by the system shell with root privileges. This can be achieved during the wireless setup phase, which typically occurs when the device is being configured for the first time or when the network settings are being changed.
Potential exploitation methods include:
- Direct Command Injection: Crafting a specially formatted WPA2 key that includes shell commands.
- Network-Based Attacks: Intercepting and modifying the WPA2 configuration packets sent to the device.
- Physical Access: Directly accessing the device and inputting malicious commands during the setup process.
3. Affected Systems and Software Versions
The vulnerability specifically affects the Shenzhen Aitemi M300 Wi-Fi Repeater with the hardware model MT02. All software versions are presumed to be affected unless explicitly patched by the vendor. Users and administrators should verify the firmware version and check for updates from the manufacturer.
4. Recommended Mitigation Strategies
To mitigate this vulnerability, the following strategies are recommended:
- Firmware Update: Immediately apply any available firmware updates from Shenzhen Aitemi that address this vulnerability.
- Network Segmentation: Isolate the Wi-Fi repeater on a separate network segment to limit potential lateral movement by attackers.
- Access Control: Restrict physical and network access to the device to trusted personnel only.
- Monitoring and Logging: Implement robust monitoring and logging to detect any unusual activity or command execution on the device.
- Input Validation: Ensure that all input parameters, especially those related to network configuration, are properly validated and sanitized.
5. Impact on European Cybersecurity Landscape
The impact of this vulnerability on the European cybersecurity landscape is significant due to the widespread use of Wi-Fi repeaters in both residential and commercial settings. The ability to execute arbitrary commands as root can lead to severe consequences, including data breaches, unauthorized access, and potential disruption of services. Organizations and individuals must prioritize patching and securing these devices to prevent potential exploitation.
