CVE-2025-13299 identifies a SQL injection vulnerability in the itsourcecode Web-Based Internet Laboratory Management System version 1.0. The vulnerability resides in an unspecified function within the /user/controller.php file, where user-supplied input is improperly sanitized or validated before being incorporated into SQL queries. This flaw allows an unauthenticated remote attacker to inject malicious SQL commands, potentially enabling unauthorized access to the underlying database. The vulnerability is exploitable over the network without any user interaction or privileges, as indicated by the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N). The impact includes partial compromise of confidentiality, integrity, and availability of the database, as the CVSS vector indicates low to medium impact on these properties (VC:L/VI:L/VA:L). The exploit has been published, which increases the likelihood of exploitation despite no current reports of active attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The lack of authentication requirements and ease of exploitation make this a significant risk for organizations relying on this system for laboratory management, especially those handling sensitive or regulated data.

For European organizations, this vulnerability poses a risk of unauthorized data disclosure, data tampering, and potential service disruption within laboratory management environments. Institutions such as universities, research centers, and healthcare laboratories that use the affected system could face breaches of sensitive research data or patient information, leading to compliance violations under GDPR and other data protection regulations. The ability to execute SQL injection remotely without authentication increases the attack surface and could allow attackers to pivot further into internal networks. The medium severity rating reflects moderate impact but high exploitability, meaning attackers could leverage this vulnerability to gain footholds or exfiltrate data. Disruption of laboratory management systems could also delay critical research or diagnostic workflows, impacting operational continuity. The absence of known active exploits currently provides a window for mitigation, but the published exploit code elevates the urgency for proactive defense.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, deploy web application firewalls (WAFs) with rules targeting SQL injection patterns to block malicious payloads targeting /user/controller.php endpoints. Conduct thorough input validation and sanitization on all user inputs, especially those interacting with SQL queries, to prevent injection. Restrict network access to the laboratory management system to trusted internal IP ranges and enforce strict segmentation to limit exposure. Monitor logs for suspicious query patterns or anomalous access attempts. If possible, upgrade to a patched version once available or consider alternative laboratory management solutions with stronger security postures. Conduct security assessments and penetration tests focused on injection vulnerabilities. Educate administrators on incident response procedures in case of exploitation. Finally, maintain regular backups of critical data to enable recovery from potential data integrity attacks.
