CVE-2025-13557 identifies a SQL injection vulnerability in Campcodes Online Polling System version 1.0, specifically within the /registeracc.php script. The vulnerability arises from improper sanitization of the 'email' parameter, allowing an attacker to inject arbitrary SQL commands into the backend database query. This injection flaw can be exploited remotely without requiring authentication or user interaction, making it accessible to any attacker with network access to the polling system. The SQL injection can lead to unauthorized data disclosure, modification, or deletion, potentially compromising user data and poll integrity. The vulnerability does not require special privileges and affects only version 1.0 of the product. Although no public exploit code is currently known to be in active use, the disclosure increases the risk of exploitation. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction needed, and low impact on confidentiality, integrity, and availability, resulting in a medium severity rating of 6.9. No official patches have been linked yet, so mitigation relies on secure coding practices and input validation.

The SQL injection vulnerability can have significant impacts on organizations using Campcodes Online Polling System 1.0. Attackers could extract sensitive user information, alter poll results, or corrupt database contents, undermining the trustworthiness and confidentiality of polling data. This could lead to reputational damage, legal liabilities, and loss of stakeholder confidence, especially for organizations relying on accurate polling data for decision-making or public opinion analysis. Additionally, attackers might leverage the vulnerability as a foothold to escalate attacks within the network. The lack of authentication and user interaction requirements increases the risk of automated exploitation attempts. While the scope is limited to the affected software version, organizations that have not updated or patched their systems remain vulnerable. The absence of known active exploits currently reduces immediate risk but does not eliminate the threat, especially as exploit code may emerge following public disclosure.

To mitigate CVE-2025-13557, organizations should first verify if they are running Campcodes Online Polling System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, immediate steps include implementing strict input validation and sanitization on the 'email' parameter in /registeracc.php, ensuring that all user inputs are treated as data rather than executable code. Employing parameterized queries or prepared statements in database interactions will prevent SQL injection attacks. Additionally, deploying web application firewalls (WAFs) with rules targeting SQL injection patterns can provide a temporary protective layer. Regularly monitoring logs for suspicious query patterns and failed injection attempts can help detect exploitation attempts early. Organizations should also conduct security audits and code reviews of their polling system to identify and remediate similar vulnerabilities. Finally, restricting network access to the polling system to trusted IPs and enforcing least privilege principles on database accounts can limit potential damage.
