CVE-2022-45207: n/a in n/a
Jeecg-boot v3.4.3 was discovered to contain a SQL injection vulnerability via the component updateNullByEmptyString.
AI Analysis
Technical Summary
CVE-2022-45207 is a critical SQL injection vulnerability identified in Jeecg-boot version 3.4.3, specifically within the component updateNullByEmptyString. Jeecg-boot is an open-source rapid development platform based on Java, widely used for enterprise applications. The vulnerability arises due to improper sanitization of user inputs in the SQL query construction process, allowing an attacker to inject malicious SQL code. This flaw corresponds to CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). Exploitation requires no authentication or user interaction, and the attack vector is network-based (AV:N), meaning it can be triggered remotely over the network. The vulnerability has a CVSS 3.1 base score of 9.8, indicating critical severity, with high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). An attacker exploiting this vulnerability can execute arbitrary SQL commands, potentially leading to unauthorized data disclosure, data manipulation, or complete compromise of the backend database. Although no known exploits are currently reported in the wild, the ease of exploitation and the critical impact make this a significant threat. No official patches or vendor advisories are listed, which may delay remediation efforts. Given the nature of Jeecg-boot as a development framework, the vulnerability could affect multiple applications built on this platform if they use the vulnerable component without proper input validation or parameterized queries.
Potential Impact
For European organizations, the impact of CVE-2022-45207 can be severe, especially for those relying on Jeecg-boot-based applications in sectors such as finance, healthcare, manufacturing, and public administration. Successful exploitation can lead to unauthorized access to sensitive personal and corporate data, violating GDPR requirements and potentially resulting in significant regulatory fines and reputational damage. Data integrity could be compromised, leading to corrupted records or fraudulent transactions, while availability could be disrupted through destructive SQL commands or denial-of-service conditions. The critical nature of the vulnerability means attackers can fully control the database backend, which may also serve as a pivot point for further network intrusion. Given the lack of authentication requirements, attackers can exploit this vulnerability remotely without prior access, increasing the attack surface. European organizations with legacy or custom applications built on Jeecg-boot are particularly at risk, especially if they have not implemented additional security controls such as web application firewalls or input validation layers.
Mitigation Recommendations
1. Immediate code review and refactoring of the updateNullByEmptyString component to implement parameterized queries or prepared statements, eliminating direct concatenation of user inputs into SQL commands. 2. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable component. 3. Conduct comprehensive security testing, including automated and manual penetration tests focusing on SQL injection vectors in all applications using Jeecg-boot. 4. Implement strict input validation and sanitization at both client and server sides to reject malicious payloads before they reach the database layer. 5. Monitor database logs and application logs for unusual query patterns or failed injection attempts to detect exploitation attempts early. 6. If possible, isolate and restrict database user privileges for applications using Jeecg-boot to minimize the impact of a successful injection. 7. Engage with the Jeecg-boot community or maintainers to obtain or contribute patches addressing this vulnerability. 8. Educate development teams on secure coding practices related to database interactions to prevent similar vulnerabilities in future releases.
