CVE-2025-11342 is a SQL injection vulnerability identified in version 1.0 of the code-projects Online Course Registration system. The flaw exists in the /admin/edit-course.php script where the coursecode parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection can manipulate backend database queries, potentially exposing or altering sensitive course registration data. The vulnerability is remotely exploitable but requires the attacker to have high-level privileges (likely administrative access) to the system, which limits the attack vector to insiders or compromised accounts. The CVSS 4.0 vector indicates no user interaction is needed, no scope change occurs, and the vulnerability impacts confidentiality, integrity, and availability to a low degree. Although no known exploits are currently active in the wild, proof-of-concept code has been publicly released, increasing the risk of exploitation. The lack of available patches at the time of publication means organizations must rely on compensating controls. The vulnerability primarily threatens the integrity and confidentiality of course registration data, which could lead to unauthorized data disclosure or modification, potentially disrupting academic operations.

For European organizations, especially educational institutions using code-projects Online Course Registration 1.0, this vulnerability poses a risk of unauthorized data access and modification within course registration systems. Attackers with administrative credentials could exploit the SQL injection to extract sensitive student or course data, alter course details, or disrupt registration processes. This could lead to privacy violations under GDPR, reputational damage, and operational disruptions during critical enrollment periods. Although exploitation requires high privileges, insider threats or compromised admin accounts increase risk. The impact on availability is limited but could still affect service continuity. Given the public availability of exploit code, the window for exploitation may widen, emphasizing the need for prompt mitigation. The medium severity rating reflects these factors, but the actual impact depends on the deployment scale and sensitivity of the data managed by the affected systems.

1. Immediately restrict access to the /admin/edit-course.php interface to trusted administrators only, ideally via network segmentation or VPN access. 2. Implement strong authentication and monitoring for administrative accounts to detect and prevent credential compromise. 3. Apply input validation and parameterized queries or prepared statements in the coursecode parameter to prevent SQL injection. 4. Monitor logs for suspicious SQL errors or unusual admin activity that could indicate exploitation attempts. 5. If available, apply vendor patches or updates addressing this vulnerability as soon as they are released. 6. Conduct regular security assessments and code reviews of the Online Course Registration system to identify and remediate similar injection flaws. 7. Educate administrators on the risks of SQL injection and the importance of safeguarding credentials. 8. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the vulnerable parameter.
