CVE-2025-14668 is a SQL injection vulnerability identified in campcodes Advanced Online Examination System version 1.0. The vulnerability resides in the /query/loginExe.php script, where the Username parameter is improperly sanitized, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables attackers to execute arbitrary SQL commands against the backend database, potentially leading to unauthorized data disclosure, modification, or deletion. The vulnerability is exploitable over the network with low attack complexity and no privileges required, increasing its risk profile. The CVSS 4.0 score of 6.9 reflects a medium severity, considering limited impact on confidentiality, integrity, and availability but ease of exploitation. The exploit code has been publicly disclosed, although no active exploitation in the wild has been reported yet. This vulnerability threatens the integrity of examination data, user credentials, and system availability, which are critical for the trustworthiness of online examination platforms. The lack of vendor patches or mitigations at this time necessitates immediate defensive measures by administrators.

For European organizations, especially educational institutions and certification bodies relying on campcodes Advanced Online Examination System 1.0, this vulnerability poses significant risks. Attackers could extract sensitive candidate information, alter exam results, or disrupt examination services, undermining the credibility of certification processes. Data breaches could lead to privacy violations under GDPR, resulting in legal and financial repercussions. The integrity of examination data is critical; manipulation could facilitate fraud or unfair advantages. Availability impacts could cause examination delays or cancellations, affecting institutional reputation. The medium severity rating suggests moderate but tangible risks, especially given the public availability of exploit code. Organizations lacking timely patching or mitigations are at elevated risk of targeted attacks or opportunistic exploitation.

Organizations should immediately implement strict input validation and sanitization on the Username parameter to prevent SQL injection. Employing parameterized queries or prepared statements in the loginExe.php script is essential to eliminate injection vectors. Network-level protections such as Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns can provide interim defense. Monitoring logs for suspicious login attempts or anomalous database queries is advised. Since no official patches are currently available, organizations should engage with the vendor for updates and consider isolating or restricting access to the vulnerable system. Conducting a thorough security audit of the entire application for similar injection flaws is recommended. Additionally, enforcing least privilege database access and regular backups will mitigate potential damage from exploitation.
