CVE-2025-5329 identifies a critical SQL Injection vulnerability in Martcode Software Inc.'s Delta Course Automation platform, a software product used for managing course automation processes. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), allowing attackers to inject malicious SQL code. This flaw enables unauthenticated remote attackers to execute arbitrary SQL queries on the backend database, potentially leading to full compromise of the database contents, including unauthorized data disclosure, data modification, or deletion, and disruption of service. The CVSS v3.1 base score of 9.8 reflects the vulnerability's ease of exploitation (network vector, no privileges or user interaction required) and its severe impact on confidentiality, integrity, and availability. The affected versions include all versions up to 04022026, with no patches or vendor responses available at the time of disclosure. The lack of vendor engagement increases the risk as organizations cannot rely on official fixes. Exploitation could allow attackers to bypass authentication, extract sensitive information such as user credentials or course data, manipulate records, or cause denial of service by corrupting the database. This vulnerability is particularly dangerous in educational or training environments where Delta Course Automation is deployed, as it may expose personal data of students and staff or disrupt critical academic operations.

For European organizations, the impact of CVE-2025-5329 is significant. Educational institutions, training centers, and enterprises using Delta Course Automation risk severe data breaches involving personal identifiable information (PII), academic records, and proprietary course content. The integrity of course data can be compromised, leading to misinformation or fraudulent records. Availability may be affected if attackers execute destructive SQL commands, causing downtime and operational disruption. Given the critical CVSS score and no available patches, attackers can exploit this vulnerability remotely without authentication or user interaction, increasing the likelihood of widespread attacks. Regulatory compliance risks are also heightened under GDPR due to potential exposure of sensitive personal data. The reputational damage and financial penalties from data breaches could be substantial. Furthermore, the lack of vendor response means organizations must rely on internal mitigations and monitoring to defend against exploitation.

1. Immediately implement strict input validation and sanitization on all user-supplied data fields interacting with the Delta Course Automation backend. 2. Refactor or patch the application code to use parameterized queries or prepared statements to prevent SQL injection. 3. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the affected application. 4. Restrict database user permissions to the minimum necessary to limit the impact of any successful injection. 5. Monitor application and database logs for unusual query patterns or errors indicative of injection attempts. 6. Network segmentation should isolate the Delta Course Automation servers from broader enterprise networks to limit lateral movement. 7. Conduct regular security assessments and penetration testing focused on injection vulnerabilities. 8. Engage with Martcode Software Inc. for updates or patches and subscribe to threat intelligence feeds for emerging exploit information. 9. Prepare incident response plans specifically addressing potential SQL injection exploitation scenarios. 10. If feasible, consider migrating to alternative course automation solutions with better security track records until a patch is available.
