Technical Analysis

CVE-2025-6738 is a SQL Injection vulnerability identified in the huija bicycleSharingServer product, specifically affecting the function userDao.selectUserByUserNameLike within the UserServiceImpl.java file. The vulnerability arises due to improper sanitization or validation of the 'Username' argument, allowing an attacker to manipulate SQL queries executed by the server. This flaw enables remote attackers to inject malicious SQL code without requiring authentication or user interaction, potentially leading to unauthorized data access or modification. The product uses a rolling release model, which complicates version tracking and patch management, as no fixed version numbers are provided for affected or fixed releases. The vulnerability has been publicly disclosed, but no known exploits have been observed in the wild yet. The CVSS 4.0 base score is 5.3, indicating a medium severity level, with attack vector network (remote), low attack complexity, no privileges required, no user interaction, and low impact on confidentiality, integrity, and availability. The vulnerability's exploitation could allow attackers to retrieve sensitive user data or manipulate backend databases, undermining the integrity and confidentiality of the system. However, the limited impact scores suggest that the vulnerability might be constrained by other mitigating factors such as partial query control or limited database privileges. Given the critical nature of SQL Injection vulnerabilities generally, this specific case appears to have some mitigating conditions reducing its overall severity.

Potential Impact

For European organizations deploying the huija bicycleSharingServer, this vulnerability poses a risk of unauthorized access to user data, including personal information of bicycle-sharing service users. Exploitation could lead to data breaches, loss of customer trust, and regulatory non-compliance, particularly under GDPR requirements for protecting personal data. The ability to remotely exploit the vulnerability without authentication increases the risk profile, especially for public-facing services. However, the medium severity and low impact on confidentiality, integrity, and availability suggest that while data exposure is possible, the scope might be limited. Still, attackers could leverage this flaw as an initial foothold for further attacks or lateral movement within the network. Disruption of service or data manipulation could also affect operational continuity of bicycle-sharing services, impacting urban mobility solutions. The rolling release nature of the product may delay patch deployment, increasing exposure time. Overall, European organizations should consider this vulnerability a moderate threat that requires timely mitigation to prevent potential data breaches and service disruptions.

Mitigation Recommendations

To mitigate CVE-2025-6738, organizations should implement the following specific measures: 1) Conduct immediate code review and refactoring of the userDao.selectUserByUserNameLike function to ensure proper parameterized queries or prepared statements are used, eliminating direct concatenation of user input into SQL commands. 2) Employ input validation and sanitization techniques on the 'Username' parameter to restrict input to expected formats and characters. 3) Monitor and audit database query logs for unusual or suspicious SQL patterns indicative of injection attempts. 4) Implement Web Application Firewalls (WAFs) with rules targeting SQL Injection patterns specific to the bicycleSharingServer endpoints. 5) Engage with the huija vendor or community to obtain updates or patches, given the rolling release model, and establish a process for continuous integration of security fixes. 6) Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. 7) Conduct penetration testing focusing on SQL Injection vectors to validate the effectiveness of mitigations. 8) Educate development teams on secure coding practices to prevent recurrence of similar vulnerabilities.
