CVE-2025-6154 is a critical SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Hostel Management System, specifically within the /includes/login.inc.php file. The vulnerability arises from improper sanitization or validation of the 'student_roll_no' parameter, which is used in SQL queries. An attacker can manipulate this parameter remotely without any authentication or user interaction to inject malicious SQL code. This can lead to unauthorized access to the backend database, allowing attackers to read, modify, or delete sensitive data such as student records, login credentials, or other confidential information stored within the system. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits have been observed in the wild yet. The CVSS 4.0 score of 6.9 (medium severity) reflects the ease of remote exploitation without privileges or user interaction, but with limited impact on confidentiality, integrity, and availability, possibly due to partial mitigations or the specific context of the injection. The vulnerability affects only version 1.0 of the PHPGurukul Hostel Management System, a niche application used primarily for managing hostel accommodations and related student data, often deployed in educational institutions. Given the nature of the vulnerability, attackers could leverage it to compromise the integrity and confidentiality of student data, potentially leading to data breaches or unauthorized administrative access.

For European organizations, particularly educational institutions and universities using the PHPGurukul Hostel Management System, this vulnerability poses a significant risk to the confidentiality and integrity of student and staff data. Exploitation could result in unauthorized disclosure of personal information, manipulation of records, or disruption of hostel management operations. This could lead to regulatory non-compliance under GDPR due to data breaches, reputational damage, and potential operational downtime. Although the system is specialized and may not be widely deployed across Europe, institutions relying on this software without proper patching or mitigations are vulnerable. The remote, unauthenticated nature of the exploit increases the risk of automated attacks or targeted intrusions. Additionally, compromised systems could be used as pivot points for further attacks within institutional networks, amplifying the impact.

1. Immediate upgrade or patching: Organizations should verify if a patched version or vendor-provided fix is available for PHPGurukul Hostel Management System 1.0 and apply it promptly. 2. Input validation and parameterized queries: If source code access is available, developers should implement strict input validation and use prepared statements or parameterized queries to prevent SQL injection. 3. Web application firewall (WAF): Deploy a WAF with rules specifically designed to detect and block SQL injection attempts targeting the 'student_roll_no' parameter. 4. Network segmentation: Isolate the hostel management system from critical institutional networks to limit lateral movement in case of compromise. 5. Monitoring and logging: Enable detailed logging of database queries and web application access to detect suspicious activities related to SQL injection attempts. 6. Access control: Restrict database user privileges to the minimum necessary to reduce the impact of a successful injection. 7. Incident response readiness: Prepare for potential exploitation by having incident response plans and backups in place to restore affected systems quickly.
