CVE-2025-6405 is a critical SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Teacher Record Management System, specifically within the /admin/edit-teacher-detail.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is susceptible to malicious input manipulation. An attacker can remotely exploit this flaw without requiring any authentication or user interaction, by crafting specially designed requests to the vulnerable parameter. Successful exploitation allows the attacker to execute arbitrary SQL commands against the backend database, potentially leading to unauthorized data disclosure, data modification, or even complete compromise of the database integrity and availability. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been observed in the wild yet. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the ease of remote exploitation without privileges or user interaction, but with limited impact on confidentiality, integrity, and availability (each rated low). The absence of a patch or mitigation from the vendor at this time further elevates the risk for organizations using this system. Given that this system manages sensitive teacher records, exploitation could lead to exposure or manipulation of personal and professional data, impacting educational institutions' operational security and privacy compliance.

For European organizations, particularly educational institutions and administrative bodies using the Campcodes Online Teacher Record Management System, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to sensitive teacher records, including personal identification data, employment history, and potentially sensitive performance or disciplinary information. This could result in privacy violations under GDPR, reputational damage, and operational disruptions. Furthermore, attackers could alter or delete records, undermining data integrity and trustworthiness of educational records. In a broader context, compromised systems could be leveraged as pivot points for further network intrusion or ransomware attacks, especially in interconnected educational networks. The impact is heightened in countries with large deployments of this software or where digital record management in education is heavily relied upon. The public disclosure of the vulnerability increases the urgency for mitigation to prevent exploitation attempts.

Given the lack of an official patch, European organizations should implement immediate compensating controls. First, restrict access to the /admin/edit-teacher-detail.php endpoint by IP whitelisting or VPN-only access to limit exposure to trusted networks. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection patterns targeting the 'editid' parameter. Conduct thorough input validation and sanitization on all user-supplied inputs at the application level, if source code access and modification are possible. Monitor web server and database logs for anomalous queries or repeated access attempts to the vulnerable endpoint. Employ network segmentation to isolate the management system from critical infrastructure. Additionally, organizations should prepare for incident response by backing up databases securely and verifying backup integrity. Engage with the vendor for updates or patches and plan for an upgrade or migration to a secure system version once available. Finally, raise awareness among IT staff about the vulnerability and ensure timely application of any future security advisories.
