The Hengan Weighing Management Information Query Platform version 2019-2021 53.25 contains a critical SQL injection vulnerability that poses significant security risks to organizations relying on this weighing management system. This vulnerability specifically affects the search_user.aspx page where the tuser_Number parameter is improperly validated and sanitized, allowing malicious actors to inject arbitrary SQL commands into the database query execution process. The vulnerability exists within a platform commonly used in industrial and commercial settings for managing weighing operations and user access control, making it a prime target for attackers seeking to compromise sensitive operational data.
The technical flaw manifests through improper input validation of the tuser_Number parameter which is used to search for user records within the system. When an attacker submits malicious SQL payload through this parameter, the application fails to properly escape or parameterize the input before incorporating it into database queries. This allows attackers to manipulate the SQL execution flow and potentially extract, modify, or delete sensitive data from the underlying database. The vulnerability is classified as a classic SQL injection flaw that falls under CWE-89 - Improper Neutralization of Special Elements used in an SQL Command, which is a fundamental weakness in database query construction that has been documented for decades in cybersecurity literature.
The operational impact of this vulnerability extends beyond simple data theft as it can enable attackers to gain unauthorized access to user accounts, manipulate weighing records, and potentially disrupt critical industrial operations. In industrial environments where weighing systems control inventory management, quality control, and financial transactions, such a vulnerability could lead to significant financial losses, operational disruptions, and compliance violations. The attack surface is particularly concerning given that this is a management information platform that likely contains sensitive user credentials, operational logs, and potentially financial data related to weighing transactions. Attackers could leverage this vulnerability to escalate privileges, create backdoor accounts, or establish persistent access to the system.
Organizations using this platform should immediately implement multiple layers of mitigation strategies to address this vulnerability. The primary remediation involves implementing proper input validation and parameterized queries throughout the application code, specifically ensuring that all user inputs are properly escaped or parameterized before database execution. Security controls should include web application firewalls that can detect and block SQL injection patterns, input sanitization at the application level, and comprehensive database access controls that limit the privileges of database accounts used by the application. Additionally, regular security assessments and penetration testing should be conducted to identify similar vulnerabilities within the application architecture, while adherence to secure coding practices such as those outlined in the OWASP Top Ten and NIST cybersecurity frameworks should be maintained. The vulnerability also aligns with ATT&CK technique T1071.004 - Application Layer Protocol: DNS, as attackers may use DNS-based exfiltration techniques to extract data from compromised systems, though the primary attack vector remains direct SQL injection. Organizations should also consider implementing database activity monitoring solutions to detect anomalous SQL query patterns that may indicate exploitation attempts.
