CVE-2025-3957 is a SQL Injection vulnerability identified in version 1.0 of the opplus springboot-admin product. The vulnerability arises from improper handling of the 'order' argument within the SQL mapping file located at \src\main\resources\mapper\sys\SysLogDao.xml. This improper sanitization or validation allows an attacker to inject malicious SQL code remotely, potentially manipulating database queries executed by the application. The vulnerability does not require user interaction and can be exploited over the network without authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:L/UI:N). The CVSS 4.0 base score is 5.3, categorized as medium severity, reflecting limited impact on confidentiality, integrity, and availability (VC:L/VI:L/VA:L). The vulnerability affects only version 1.0 of the product, and no patches or fixes have been publicly disclosed yet. Although the exploit has been publicly disclosed, there are no known active exploits in the wild at the time of publication. The vulnerability's exploitation could allow attackers to read, modify, or delete data within the backend database, potentially leading to data leakage, unauthorized data manipulation, or disruption of service depending on the database's role in the application. The vulnerability is notable because springboot-admin is a management and monitoring tool for Spring Boot applications, which are widely used in enterprise environments. The presence of this vulnerability in a monitoring tool could allow attackers to pivot into other parts of the infrastructure if leveraged effectively.

For European organizations, the impact of CVE-2025-3957 depends largely on the adoption of opplus springboot-admin version 1.0 within their IT environments. Organizations using this specific version are at risk of unauthorized data access and manipulation due to SQL injection, which could compromise sensitive operational data, logs, or configuration information managed by the tool. This could lead to data integrity issues, loss of trust in monitoring data, and potential disruption of application monitoring and management processes. Given that springboot-admin is often used in critical application monitoring, exploitation could indirectly affect availability and operational continuity. Additionally, if attackers leverage this vulnerability to gain deeper access, it could facilitate lateral movement within networks, increasing the risk of broader compromise. The medium severity rating suggests that while the vulnerability is exploitable remotely without user interaction, the overall impact on confidentiality, integrity, and availability is limited but non-negligible. European organizations in sectors such as finance, manufacturing, and public services that rely on Spring Boot applications and associated monitoring tools should be particularly vigilant. The lack of known active exploits reduces immediate risk but does not eliminate the threat, especially as public exploit code is available.

1. Immediate mitigation should involve upgrading or patching the opplus springboot-admin product to a version that addresses this vulnerability once available. Since no patches are currently disclosed, organizations should contact the vendor for guidance or apply vendor-provided workarounds. 2. Implement strict input validation and sanitization on all parameters, especially those related to SQL queries such as the 'order' argument, to prevent injection attacks. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the vulnerable endpoint or parameter. 4. Restrict network access to the springboot-admin interface to trusted IP addresses or internal networks only, minimizing exposure to external attackers. 5. Monitor application logs and database query logs for unusual or suspicious activity indicative of SQL injection attempts. 6. Conduct security assessments and penetration testing focused on injection vulnerabilities in the application environment. 7. Consider isolating the monitoring tool environment from critical production systems to limit potential lateral movement in case of compromise. 8. Educate development and operations teams on secure coding practices and the importance of timely patching for third-party components.
