CVE-2025-10848 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Society Membership Information System, specifically affecting the /check_student.php endpoint. The vulnerability arises from improper sanitization or validation of the 'student_id' parameter, allowing an attacker to inject malicious SQL code. This injection can be performed remotely without requiring user interaction or authentication, making it accessible to unauthenticated remote attackers. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is low, suggesting that while the injection can manipulate or access some data, it may not lead to full system compromise or widespread data leakage. No patches or fixes have been publicly linked yet, and no known exploits are reported in the wild, although public exploit code is available, increasing the risk of exploitation. The vulnerability primarily affects the processing of the 'student_id' parameter in the membership system, which likely stores sensitive membership and student information, potentially exposing personal data or allowing unauthorized data manipulation.

For European organizations using the Campcodes Society Membership Information System, this vulnerability poses a risk of unauthorized data access or modification within membership databases. Given the nature of the system, which likely contains personal and membership-related information, exploitation could lead to breaches of personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The medium severity and low impact on availability reduce the likelihood of service disruption but do not eliminate the risk of data integrity compromise or unauthorized data disclosure. Organizations relying on this system for managing student or member information may face targeted attacks aiming to extract or alter membership records. The availability of public exploit code increases the risk of opportunistic attacks, especially if the system is exposed to the internet without adequate network protections. Additionally, since no patches are currently available, organizations must rely on mitigation strategies to reduce exposure until a fix is released.

1. Immediate implementation of input validation and parameterized queries or prepared statements in the /check_student.php script to prevent SQL injection. 2. Employ Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns targeting the 'student_id' parameter. 3. Restrict network access to the membership system, limiting exposure to trusted internal networks or VPNs to reduce remote attack surface. 4. Conduct thorough code reviews and security testing on all input handling components of the system, especially those processing user-supplied parameters. 5. Monitor logs for unusual query patterns or repeated access attempts to /check_student.php that may indicate exploitation attempts. 6. Plan and prioritize patch management once an official fix is released by Campcodes, ensuring timely deployment. 7. Educate system administrators and developers about the risks of SQL injection and secure coding practices to prevent similar vulnerabilities in future versions.
