CVE-2025-13556 is a SQL injection vulnerability identified in Campcodes Online Polling System version 1.0. The vulnerability resides in the /admin/checklogin.php file, where the 'myusername' parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection flaw can be exploited remotely without requiring authentication or user interaction, enabling attackers to manipulate backend database queries. Potential consequences include unauthorized data access, data modification, or disruption of service, impacting the confidentiality, integrity, and availability of the polling system's data. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the vulnerability's ease of exploitation and moderate impact. Although no active exploitation has been reported, the public availability of exploit code increases the likelihood of attacks. The vulnerability affects only version 1.0 of the product, which is used for conducting online polls, possibly in organizational or governmental contexts. No official patches have been released yet, so mitigation relies on secure coding practices such as input validation, use of parameterized queries, and restricting access to the admin interface. Monitoring logs for suspicious activity and applying network-level protections can also help reduce risk.

For European organizations using Campcodes Online Polling System 1.0, this vulnerability poses a risk of unauthorized access to sensitive polling data, manipulation of poll results, or disruption of polling services. Such impacts could undermine trust in polling processes, especially in politically sensitive environments or organizations relying on accurate polling data for decision-making. Confidentiality breaches could expose voter or participant information, while integrity violations could alter poll outcomes. Availability impacts might disrupt ongoing polling activities, affecting organizational operations. Given the remote exploitation capability without authentication, attackers can target vulnerable systems over the internet, increasing exposure. The medium severity indicates a moderate but tangible risk, particularly for entities where polling data integrity is critical. European organizations involved in elections, public opinion research, or internal decision-making processes using this system are at heightened risk. The lack of patches means organizations must act quickly to implement mitigations to prevent exploitation.

1. Immediately review and update the /admin/checklogin.php script to implement strict input validation and sanitization for the 'myusername' parameter. 2. Refactor database queries to use parameterized statements or prepared queries to prevent SQL injection. 3. Restrict access to the admin interface by IP whitelisting, VPNs, or other network access controls to limit exposure. 4. Monitor application and database logs for unusual query patterns or repeated failed login attempts that may indicate exploitation attempts. 5. If possible, isolate the polling system behind web application firewalls (WAFs) configured to detect and block SQL injection payloads. 6. Conduct a thorough security audit of the entire application to identify and remediate any other injection or input validation issues. 7. Engage with the vendor or community to obtain or develop official patches or updates addressing this vulnerability. 8. Educate administrators and developers about secure coding practices to prevent similar vulnerabilities in future versions. 9. Consider temporary disabling or limiting the use of the vulnerable polling system until mitigations are fully implemented. 10. Implement regular backups of polling data to enable recovery in case of data corruption or loss.
