This critical vulnerability exists in Tecno 4G Portable WiFi TR118 device firmware version V008-20220830 within the SMS Check functionality. The vulnerability manifests through the /goform/goform_get_cmd_process endpoint which processes SMS-related commands. The specific flaw occurs when the order_by parameter is manipulated, allowing an attacker to inject malicious SQL commands into the backend database query execution. This represents a classic sql injection vulnerability that can be exploited remotely without requiring physical access to the device or any authentication credentials. The vulnerability affects the device's ability to properly sanitize user input before incorporating it into database queries, creating a pathway for unauthorized data access and potential system compromise.
The technical implementation of this vulnerability stems from inadequate input validation and parameter handling within the web interface component. When the order_by argument is submitted through the SMS Check functionality, the application fails to properly escape or filter special characters that could alter the intended SQL query structure. This allows an attacker to manipulate the database query execution flow and potentially extract sensitive information, modify database records, or even execute administrative commands on the device. The attack surface is particularly concerning as it operates through the device's web management interface, making it accessible to anyone who can reach the device's IP address over the network.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with potential access to the device's core functionalities and user data. An attacker could leverage this sql injection to gain unauthorized access to stored SMS messages, device configuration settings, network credentials, or other sensitive information stored within the device's database. Additionally, the vulnerability could enable more sophisticated attacks such as privilege escalation or even remote code execution depending on the database system and underlying architecture. Given that this is a portable WiFi device, the attack surface includes not just the device itself but also any networks it connects to, potentially allowing lateral movement attacks.
Security practitioners should consider this vulnerability in the context of CWE-89 which specifically addresses sql injection flaws, and align it with ATT&CK technique T1190 for exploit via web application. The lack of vendor response to early disclosure attempts creates a particularly dangerous scenario where no official patch or mitigation exists, leaving users exposed to potential exploitation. Organizations should implement network segmentation to isolate these devices from critical systems and monitor for suspicious network traffic patterns. Immediate mitigation strategies include firewall rules to block access to the vulnerable endpoint and network-based intrusion detection systems configured to identify sql injection patterns. The vulnerability highlights the importance of secure coding practices and proper input validation in embedded web interfaces, particularly in IoT devices where patch management may be limited or non-existent.
