CVE-2025-13583 identifies a SQL injection vulnerability in the code-projects Question Paper Generator version 1.0, specifically within the /signupscript.php file's POST parameter handler for the 'Fname' argument. SQL injection occurs when user input is improperly sanitized, allowing attackers to inject malicious SQL statements that the backend database executes. This vulnerability is remotely exploitable without requiring authentication or user interaction, making it highly accessible to attackers. The CVSS 4.0 score of 6.9 (medium severity) reflects the moderate impact on confidentiality, integrity, and availability, with low complexity and no privileges needed. Exploiting this flaw could allow attackers to read, modify, or delete sensitive data stored in the database, potentially compromising user data or application functionality. The vulnerability affects only version 1.0 of the product, and no official patches or updates have been released yet. The public availability of exploit code increases the likelihood of exploitation attempts. The affected software is typically used in educational contexts for generating question papers, which may contain sensitive academic data. The lack of secure coding practices in input validation and parameter handling is the root cause. Organizations using this software should urgently assess exposure and implement mitigations to prevent exploitation.

For European organizations, particularly educational institutions and testing centers using code-projects Question Paper Generator 1.0, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized access to sensitive academic data, including student information and exam content, undermining data confidentiality and integrity. Attackers could manipulate or delete records, disrupting examination processes and damaging institutional reputation. The remote and unauthenticated nature of the exploit increases the attack surface, potentially allowing widespread automated attacks. Data breaches could also lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. The impact on availability is moderate but could still disrupt critical academic operations. Organizations relying on this software without proper compensating controls are at heightened risk. The public disclosure of exploit code further elevates the threat level, necessitating immediate attention to prevent exploitation within European educational ecosystems.

Since no official patch is currently available, European organizations should implement immediate compensating controls. First, apply strict input validation and sanitization on the 'Fname' POST parameter, ensuring only expected characters are accepted. Employ parameterized queries or prepared statements to prevent SQL injection attacks. Conduct a thorough code review of the /signupscript.php file and related components to identify and remediate similar vulnerabilities. Restrict access to the affected application via network segmentation and firewall rules to limit exposure. Enable detailed logging and monitoring of database queries and application logs to detect suspicious activity indicative of exploitation attempts. Educate developers and administrators about secure coding practices to prevent future vulnerabilities. Plan for an upgrade or migration to a patched or alternative solution once available. Additionally, perform regular backups of critical data to enable recovery in case of data tampering or loss.
