CVE-2025-10811 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Hostel Management System, specifically within the file /justines/admin/mod_comments/index.php at the 'view' parameter. The vulnerability arises from improper sanitization or validation of the 'ID' argument, allowing an attacker to manipulate this input to inject malicious SQL code. This flaw can be exploited remotely without requiring authentication or user interaction, making it particularly dangerous. Successful exploitation could allow an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data disclosure, data modification, or deletion. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, no privileges or user interaction needed, but limited impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the existence of a published exploit increases the risk of active attacks. The vulnerability affects only version 1.0 of the product, which is a niche hostel management system likely used by educational institutions or accommodation providers to manage bookings, comments, and administrative functions. The lack of available patches or vendor advisories suggests that affected organizations must implement mitigations promptly to reduce exposure.

For European organizations, especially educational institutions, hostels, or small accommodation providers using the affected Hostel Management System version 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive data such as user comments, booking details, or administrative information stored in the database. This could result in data breaches violating GDPR requirements, leading to regulatory penalties and reputational damage. Additionally, attackers could manipulate or delete data, disrupting operational continuity and trust in the system. Since the vulnerability requires no authentication and can be exploited remotely, attackers can target exposed web interfaces directly. The medium severity rating indicates a moderate but tangible threat, particularly if the system contains personally identifiable information (PII) or financial data. The lack of patches means organizations must rely on compensating controls until an official fix is available. The impact is heightened in environments where the Hostel Management System is integrated with other internal systems or where database segregation is weak, potentially allowing lateral movement or broader compromise.

1. Immediate mitigation should include restricting external access to the vulnerable module (/justines/admin/mod_comments/index.php) via network controls such as firewalls or VPNs, limiting exposure to trusted internal users only. 2. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'view' parameter. 3. Conduct input validation and sanitization on all user-supplied parameters, especially the 'ID' argument, using parameterized queries or prepared statements if source code access is available. 4. Monitor web server and database logs for suspicious activity indicative of SQL injection attempts. 5. If possible, upgrade to a patched version once released or consider migrating to alternative hostel management solutions with active security support. 6. Perform regular security assessments and penetration testing focused on web application inputs to identify similar injection flaws. 7. Educate administrators about the risks and signs of exploitation to enable rapid incident response. 8. Backup critical data regularly and ensure backups are isolated to enable recovery in case of data tampering or loss.
