CVE-2025-12342 identifies a SQL injection vulnerability in Serdar Bayram Ghost Hot Spot versions up to 20251014. The vulnerability resides in an unspecified function within the /Auth.php file of the Login component, which processes user authentication requests. Due to improper sanitization or validation of input parameters, an attacker can remotely inject malicious SQL code into backend database queries. This injection can lead to unauthorized data retrieval, modification, or deletion, compromising confidentiality, integrity, and potentially availability of the system. The attack vector requires no authentication or user interaction, increasing the risk of automated exploitation. The vulnerability has a CVSS 4.0 base score of 6.9 (medium severity), reflecting its network accessibility, low attack complexity, and lack of required privileges. Although an exploit has been published, no active exploitation has been observed in the wild. The vendor has not issued any patches or advisories, leaving users exposed. The absence of vendor response complicates remediation efforts, emphasizing the need for defensive controls and monitoring. This vulnerability is particularly concerning for environments where Ghost Hot Spot manages critical authentication or network access functions, as compromise could lead to broader network infiltration or data breaches.

For European organizations, exploitation of this SQL injection vulnerability could result in unauthorized access to sensitive authentication data or user credentials managed by Ghost Hot Spot. This could facilitate lateral movement within networks, data exfiltration, or disruption of network access services. Organizations in sectors such as telecommunications, public Wi-Fi providers, and enterprises relying on Ghost Hot Spot for network authentication are at heightened risk. The lack of vendor patches increases the window of exposure, potentially allowing attackers to develop and deploy automated exploits. Data breaches resulting from this vulnerability could lead to regulatory penalties under GDPR due to compromised personal data. Additionally, service disruptions could impact business continuity and customer trust. The medium severity rating suggests a significant but not critical threat; however, the ease of remote exploitation without authentication elevates the urgency for mitigation. European organizations with limited incident response capabilities or outdated network segmentation may face amplified impacts.

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict external access to the Ghost Hot Spot management interfaces by applying strict firewall rules and network segmentation to limit exposure. Second, deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting /Auth.php endpoints. Third, conduct thorough input validation and sanitization on all user-supplied data if customization or internal development is possible. Fourth, enable detailed logging and continuous monitoring of authentication-related activities to detect anomalous queries or repeated failed login attempts indicative of exploitation attempts. Fifth, consider isolating or replacing the affected Ghost Hot Spot component with alternative solutions if feasible. Lastly, maintain up-to-date backups and develop incident response plans specific to SQL injection attacks to minimize downtime and data loss. Organizations should also engage with cybersecurity communities to share indicators of compromise and monitor for emerging exploits.
