CVE-2025-8238 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Exam Form Submission application. The vulnerability exists in an unspecified function within the /admin/update_s2.php file. Specifically, the issue arises from improper sanitization or validation of the 'credits' parameter, which is directly used in SQL queries. This flaw allows an unauthenticated remote attacker to inject arbitrary SQL code by manipulating the 'credits' argument, potentially leading to unauthorized data access, data modification, or even full compromise of the underlying database. The vulnerability does not require any user interaction or authentication, making it highly exploitable. The CVSS 4.0 score is 6.9 (medium severity), reflecting that while the attack vector is network-based and requires no privileges or user interaction, the impact on confidentiality, integrity, and availability is limited to low levels. However, the public disclosure of the exploit increases the risk of exploitation. The vulnerability affects only version 1.0 of the Exam Form Submission product by code-projects. No official patches or mitigations have been published yet. The lack of authentication and remote exploitability make this a significant threat, especially for organizations using this software in administrative capacities where sensitive exam or student data may be stored or processed.

For European organizations using code-projects Exam Form Submission 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive academic data, including student records, exam results, and credit information. Exploitation could lead to unauthorized data disclosure, data tampering, or denial of service through database corruption or manipulation. Educational institutions and certification bodies relying on this software may face reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially if the affected systems are exposed to the internet or insufficiently segmented networks. Given the criticality of exam data and the potential for manipulation of academic records, the impact extends beyond IT systems to affect trust in educational processes and compliance with data protection laws in Europe.

Immediate mitigation steps include restricting external access to the /admin/update_s2.php endpoint through network-level controls such as firewalls or VPNs, ensuring only trusted administrators can reach the vulnerable interface. Organizations should implement web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'credits' parameter. Input validation and sanitization should be enforced at the application level, ideally by updating or patching the software once an official fix is released. Until a patch is available, consider isolating the affected system from public networks and monitoring logs for suspicious activity related to the 'credits' parameter. Regular backups of the database should be maintained to enable recovery in case of data corruption. Additionally, conducting a thorough security review of all input handling in the application is recommended to identify and remediate similar injection flaws.
