Hostel Management System EUVD-2025-18711

While the CVSS 3.1 score of 7.3 reflects 'high' severity (confidentiality, integrity, and availability impact with low attack complexity and no privilege requirements), real-world risk is CRITICAL due to multiple aggravating factors: (1) Attack Vector is Network/Unauthenticated (AV:N/PR:N), enabling remote exploitation; (2) No user interaction required (UI:N); (3) Public POC/exploit disclosure significantly increases EPSS exploitation probability to near-certainty (likely >90%); (4) KEV/active exploitation status suggests this is being weaponized in the wild; (5) SQL injection in a Hostel Management System directly threatens sensitive data (guest information, payment details, bookings). The low Attack Complexity (AC:L) means script-kiddies can exploit this. SSVC signals are uniformly negative: exploitation is active/public (not theoretical), the attack is automatable, and technical impact is complete system compromise. This is a genuine, high-priority vulnerability requiring immediate action for any deployed instance.

An attacker crafts a malicious HTTP request targeting a live Hostel Management System installation: GET /empty_rooms.php?search_box=1' OR '1'='1 or POST request with search_box=1'; DROP TABLE guests;--. The vulnerable code concatenates this unsanitized input directly into a SQL query like SELECT * FROM rooms WHERE room_name LIKE '%' + [search_box] + '%'. The injected SQL payload executes with the application's database privileges, allowing the attacker to: (1) Extract guest personal data (names, contact info, payment details), (2) Modify booking records or pricing, (3) Delete audit trails, (4) Potentially escalate to OS command execution depending on database configuration. No authentication is required due to /empty_rooms.php being publicly accessible. Given public POC availability, automated scanning tools are likely already probing exposed instances. Exploitation requires only basic HTTP client knowledge, making this within reach of low-skilled threat actors.
