The SQL injection vulnerability identified as CVE-2021-38239 affects the dataease platform prior to version 1.2.0, representing a critical security flaw that exposes the system to unauthorized data access. This vulnerability specifically manifests through the orders parameter within the API endpoint /api/sys_msg/list/1/10, where improper input validation allows malicious actors to inject arbitrary SQL commands. The flaw falls under the Common Weakness Enumeration category CWE-89, which classifies SQL injection as a persistent vulnerability that enables attackers to manipulate database queries through untrusted input. The affected application fails to properly sanitize user-supplied parameters before incorporating them into SQL execution contexts, creating an exploitable pathway for data exfiltration and system compromise.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with the capability to extract sensitive data from the underlying database through carefully crafted SQL injection payloads. The orders parameter in the specified API endpoint serves as the primary attack vector, where an attacker can manipulate the parameter value to execute unauthorized database operations. This vulnerability aligns with ATT&CK technique T1071.005, which describes application layer protocol manipulation, and T1046, covering network service scanning that can lead to privilege escalation. The vulnerability exists due to insufficient input validation and parameter sanitization, allowing attackers to bypass authentication mechanisms and potentially access confidential information such as user credentials, personal data, or system configurations.
Mitigation strategies for CVE-2021-38239 require immediate implementation of proper input validation and parameterized queries to prevent SQL injection attacks. Organizations should upgrade to dataease version 1.2.0 or later, where the vulnerability has been addressed through enhanced input sanitization and query parameterization. The recommended approach involves implementing prepared statements or parameterized queries that separate SQL code from user input, preventing malicious payloads from being executed as part of database operations. Additionally, input validation should be strengthened to reject suspicious characters and patterns commonly associated with SQL injection attacks. Security measures should include web application firewall rules to detect and block malicious requests targeting the vulnerable API endpoint, as well as regular security testing and code review processes to identify similar vulnerabilities in other application components. The remediation process should also involve monitoring database logs for unusual query patterns and implementing proper access controls to limit the potential impact of successful exploitation attempts.
