CVE-2025-5698 is a SQL Injection vulnerability identified in the Brilliance Golden Link Secondary System, specifically affecting an unknown function within the /sysframework/logSelect.htm file. The vulnerability arises from improper sanitization or validation of the 'nodename' parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring user interaction or authentication, as indicated by the CVSS vector. The vulnerability affects versions up to 20250424 of the product. Although the CVSS score is 5.3 (medium severity), the vulnerability's characteristics—remote exploitability, no user interaction, and potential for data manipulation—make it a significant concern. The exploit has been publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The vulnerability could lead to unauthorized data access, data modification, or potentially disruption of service depending on the database and application context. The lack of available patches or mitigation guidance from the vendor at this time further complicates the risk management for affected organizations.

For European organizations using the Brilliance Golden Link Secondary System, this vulnerability poses a risk of unauthorized access to sensitive data stored in backend databases, potentially including personal data protected under GDPR. Successful exploitation could compromise confidentiality and integrity of data, leading to data breaches, regulatory penalties, and reputational damage. The ability to execute arbitrary SQL commands remotely without authentication increases the attack surface, making it easier for threat actors to exploit the system. Additionally, manipulation of database queries could disrupt business operations or lead to denial of service conditions. Organizations in sectors such as manufacturing, logistics, or any industry relying on Brilliance's systems for critical operations may face operational disruptions and compliance risks. The public disclosure of the exploit details heightens the urgency for mitigation to prevent opportunistic attacks.

Given the absence of vendor patches, European organizations should implement immediate compensating controls. These include deploying Web Application Firewalls (WAFs) with custom rules to detect and block malicious SQL injection payloads targeting the 'nodename' parameter in /sysframework/logSelect.htm. Network segmentation should isolate the affected system to limit exposure. Conduct thorough input validation and sanitization on all user-supplied parameters at the application level if source code access is available. Monitor logs for unusual database query patterns or failed injection attempts. Restrict database user privileges associated with the application to the minimum necessary to limit the impact of a successful injection. Organizations should engage with Brilliance for timely patch releases and apply updates promptly once available. Additionally, conduct security awareness training for IT staff to recognize exploitation attempts and maintain incident response readiness.
