CVE-2025-51825 is a SQL injection vulnerability identified in JeecgBoot, an open-source rapid development platform widely used for enterprise applications. The vulnerability affects versions from 3.4.3 up to 3.8.0 and is located in the /jeecg-boot/online/cgreport/head/parseSql endpoint. This endpoint is responsible for parsing SQL queries for dynamic report generation. The flaw allows attackers to bypass existing SQL blacklist restrictions, which are typically implemented to prevent malicious SQL code execution. By circumventing these restrictions, an attacker can inject arbitrary SQL commands, potentially leading to unauthorized data access, data modification, or even complete compromise of the backend database. The vulnerability does not currently have a CVSS score, and no known exploits have been reported in the wild as of the publication date. However, given the nature of SQL injection vulnerabilities, the risk remains significant, especially if the affected endpoint is exposed to untrusted users or the internet. The lack of authentication requirements or user interaction details is not specified, but SQL injection flaws often can be exploited remotely if the endpoint is accessible. The vulnerability's presence in a core component of JeecgBoot used for dynamic report generation increases the attack surface, as reports often query sensitive business data. Without proper patching or mitigation, attackers could leverage this flaw to extract confidential information, alter data integrity, or disrupt application availability.

For European organizations using JeecgBoot in their enterprise environments, this vulnerability poses a substantial risk to confidentiality, integrity, and availability of critical business data. SQL injection can lead to unauthorized data disclosure, including personal data protected under GDPR, which could result in regulatory penalties and reputational damage. Data integrity could be compromised by unauthorized modification or deletion of records, affecting business operations and decision-making. Availability risks arise if attackers execute destructive SQL commands or cause database crashes. Given the widespread adoption of JeecgBoot in various sectors including finance, manufacturing, and public administration within Europe, exploitation could disrupt essential services and lead to significant operational downtime. Furthermore, the ability to bypass blacklist restrictions suggests that existing security controls may be insufficient, increasing the likelihood of successful exploitation if attackers target exposed endpoints. The absence of known exploits currently provides a window for proactive mitigation, but organizations must act swiftly to prevent potential future attacks.

European organizations should immediately audit their use of JeecgBoot versions 3.4.3 through 3.8.0 and identify any deployments exposing the /jeecg-boot/online/cgreport/head/parseSql endpoint. Since no official patches are referenced, organizations should consider the following specific mitigations: 1) Implement strict input validation and parameterized queries or prepared statements in the affected endpoint to prevent SQL injection. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns, especially those attempting to bypass blacklist filters. 3) Restrict access to the vulnerable endpoint by network segmentation, IP whitelisting, or requiring strong authentication mechanisms to reduce exposure. 4) Conduct thorough code reviews and penetration testing focused on SQL injection vectors within JeecgBoot customizations. 5) Monitor logs for unusual query patterns or errors indicative of injection attempts. 6) Engage with the JeecgBoot community or vendor for official patches or updates and apply them promptly once available. 7) Educate developers and administrators on secure coding practices and the risks of relying solely on blacklist filtering for SQL injection prevention.
