The vulnerability CVE-2022-45210 affects Jeecg-boot version 3.4.3 and represents a critical SQL injection flaw within the system's user management component. This vulnerability exists in the /sys/user/deleteRecycleBin endpoint which processes user deletion requests from the recycle bin functionality. The flaw allows attackers to manipulate database queries through improper input validation and sanitization mechanisms. The affected component handles user data removal operations and appears to directly incorporate user-supplied parameters into SQL execution contexts without adequate protection measures. This creates a pathway for malicious actors to execute arbitrary SQL commands against the underlying database system, potentially leading to complete database compromise and unauthorized access to sensitive user information.
The technical implementation of this vulnerability stems from inadequate parameter validation within the deleteRecycleBin endpoint. When users attempt to delete records from the recycle bin, the system fails to properly sanitize or escape input parameters before incorporating them into database queries. This weakness aligns with CWE-89 which defines SQL injection as the insertion of malicious SQL code into input fields that are then executed by the database. Attackers can exploit this by crafting malicious input that alters the intended SQL query structure, potentially bypassing authentication mechanisms, extracting confidential data, or modifying database contents. The vulnerability demonstrates poor input handling practices and highlights the absence of proper prepared statement usage or parameterized queries in the application's data access layer.
The operational impact of this vulnerability extends beyond simple data compromise to encompass complete system infiltration capabilities. Successful exploitation could enable attackers to extract all user credentials, personal information, and business data stored within the database. The vulnerability affects the confidentiality, integrity, and availability of the affected system, potentially leading to unauthorized access to administrative functions and complete system takeover. Organizations using this vulnerable version face significant risk of data breaches, compliance violations, and potential regulatory penalties. The attack surface is particularly concerning as it involves user management functions that typically require elevated privileges and contain sensitive operational data. This vulnerability could also serve as a stepping stone for further attacks within the network infrastructure, especially if database credentials are not properly isolated from application components.
Mitigation strategies for CVE-2022-45210 should prioritize immediate patching of the Jeecg-boot framework to version 3.4.4 or later where the SQL injection vulnerability has been addressed. Organizations must implement proper input validation and sanitization measures across all database interaction points, particularly those handling user-supplied data. The implementation of prepared statements and parameterized queries should become mandatory for all database operations to prevent direct query construction from user input. Network segmentation and database access controls should be strengthened to limit the impact of potential exploitation attempts. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other application components. Additionally, implementing web application firewalls and database activity monitoring systems can provide additional layers of defense against exploitation attempts. The vulnerability also underscores the importance of following secure coding practices and adhering to industry standards such as those defined in the OWASP Top Ten and NIST cybersecurity frameworks to prevent similar issues in future development cycles.
