CVE-2025-12928 is an SQL Injection vulnerability affecting the code-projects Online Job Search Engine version 1.0. The vulnerability resides in the /login.php script, where the username or phone parameters are improperly sanitized, allowing attackers to inject malicious SQL code. This injection flaw enables remote attackers to execute arbitrary SQL queries on the backend database without requiring authentication or user interaction. The vulnerability is exploitable over the network, making it accessible to any attacker who can reach the login endpoint. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low complexity and no privileges or user interaction needed, but with limited impact on confidentiality, integrity, and availability. The exploit code has been publicly disclosed, increasing the risk of exploitation. The lack of official patches or updates means organizations must implement immediate mitigations. The vulnerability could allow attackers to bypass authentication, extract sensitive user data, or modify database contents, potentially leading to data breaches or service disruption. This is particularly concerning for organizations relying on this job search engine to manage user credentials and personal information. The vulnerability highlights the critical need for secure coding practices such as input validation and use of prepared statements to prevent SQL injection attacks.

For European organizations using the affected Online Job Search Engine, this vulnerability poses a significant risk to the confidentiality and integrity of user data, including personal and login information. Exploitation could lead to unauthorized access to sensitive data, data leakage, or unauthorized modifications, undermining trust and potentially violating GDPR requirements. Service availability could also be impacted if attackers manipulate the database to disrupt operations. The public availability of exploit code increases the likelihood of attacks, especially targeting organizations that have not applied mitigations. Given the widespread use of online job platforms in Europe and the sensitivity of employment-related data, this vulnerability could have reputational and regulatory consequences. Organizations in sectors such as recruitment, human resources, and employment services are particularly at risk. The vulnerability's remote exploitability without authentication means attackers can operate from anywhere, increasing the threat landscape for European entities.

Organizations should immediately implement input validation and sanitization on all user-supplied data, especially the username and phone parameters in the /login.php script. Employing parameterized queries or prepared statements is critical to prevent SQL injection. If possible, upgrade to a patched version of the software once available or apply vendor-provided fixes. In the absence of official patches, consider deploying web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the login endpoint. Conduct thorough code reviews and security testing to identify and remediate similar injection flaws elsewhere in the application. Monitor logs for suspicious login attempts or anomalous database queries indicative of exploitation attempts. Additionally, restrict database user permissions to the minimum necessary to limit the impact of any successful injection. Educate development teams on secure coding practices to prevent recurrence. Finally, ensure regular backups of databases to enable recovery in case of data corruption or loss.
