Sign in to read
Exploitation Conditions	itsourcecode Free Hotel Reservation System 1.0: Remote unauthenticated attacker can exploit SQL injection via manipulated account_id parameter in /hotel/admin/mod_users/index.php?view=edit&id=8. No victim interaction required. Default installations vulnerable.
Impact	This vulnerability presents a significant real-world risk despite not appearing in CISA KEV. The CVSS score of 7.3 reflects high severity with an exploitable network attack vector (AV:N), low attack complexity (AC:L), and no required privileges (PR:N) or user interaction (UI:N). The public availability of a working proof-of-concept exploit on GitHub dramatically increases exploitation likelihood, as threat actors can readily weaponize this vulnerability without developing their own exploits. The SQL injection can lead to complete database compromise including data exfiltration, modification, or deletion. While the CVSS impact ratings are marked as Low across CIA triad, SQL injection vulnerabilities typically enable full database access, suggesting real-world impact may be more severe. Organizations running this system should treat this as a critical priority given the combination of public exploit availability, remote exploitability, and no authentication requirement.
Exploit ScenarioDerived	An unauthenticated attacker identifies a hotel website running Free Hotel Reservation System 1.0 and navigates to the administrative interface at /hotel/admin/mod_users/index.php. Using the publicly available GitHub exploit code, the attacker crafts a malicious request manipulating the account_id parameter with SQL injection payloads such as UNION-based or Boolean-based injection techniques. The attacker successfully extracts the entire user database including administrator credentials, customer personal information, and reservation details, then uses extracted admin credentials to modify reservation records or install a web shell for persistent access.

This Month Plan within 30 days. Why: MEDIUM severity (CVSS 4.0-6.9).

AnalysisAIv1 – Mar 23, 2026

SQL injection in the Free Hotel Reservation System 1.0 admin panel allows unauthenticated remote attackers to manipulate the account_id parameter and execute arbitrary SQL queries with potential for data theft, modification, and system disruption. Public exploit code exists for this vulnerability, and no patch is currently available.

Earlier versions of this analysis (1)

v1 Mar 23, 2026 - 22:15 CVSS 7.3

A SQL injection vulnerability exists in Free Hotel Reservation System version 1.0, specifically in the account_id parameter of the /hotel/admin/mod_users/index.php file. An unauthenticated remote attacker can exploit this flaw to execute arbitrary SQL commands, potentially compromising confidentiality, integrity, and availability of the database. A public proof-of-concept exploit is available on GitHub, significantly lowering the barrier to exploitation.

RemediationAI

No official patch or security advisory from itsourcecode has been referenced in the available intelligence sources, indicating the vendor may not have released an updated version addressing this vulnerability. Organizations should immediately implement input validation and parameterized queries (prepared statements) for the account_id parameter in /hotel/admin/mod_users/index.php. As an interim mitigation, restrict access to the /hotel/admin/ directory to trusted IP addresses only through web server configuration (Apache .htaccess or Nginx location blocks) and implement a web application firewall (WAF) with SQL injection signature detection. Consider migrating to an actively maintained hotel reservation system with a better security track record. Monitor database logs for suspicious query patterns and unauthorized access attempts. Refer to the vulnerability details at https://vuldb.com/?id.352476 and the exploit documentation at https://github.com/bybinyu/Vulnerability-Practice/issues/2 to understand attack patterns for detection purposes.

Technical ContextAI · show details

This vulnerability affects the Free Hotel Reservation System 1.0 developed by itsourcecode (CPE: cpe:2.3:a:itsourcecode:free_hotel_reservation_system:*:*:*:*:*:*:*:*), a PHP-based hotel reservation management application. The root cause is CWE-89 (SQL Injection), which occurs when user-supplied input from the account_id parameter in the Parameter Handler component is improperly sanitized before being used in SQL queries. This allows attackers to inject malicious SQL code that will be executed by the backend database, typically MySQL or MariaDB in PHP applications. The vulnerability exists in the administrative interface's user modification functionality, specifically when editing user records through the view=edit endpoint.

DescriptionCVE.org

A vulnerability has been found in itsourcecode Free Hotel Reservation System 1.0. This affects an unknown part of the file /hotel/admin/mod_users/index.php?view=edit&id=8 of the component Parameter Handler. The manipulation of the argument account_id leads to sql injection. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used.

Executive ViewAI

Why It Matters

A critical SQL injection vulnerability in the Free Hotel Reservation System allows unauthenticated attackers to compromise the database without authentication. With a public exploit available and no patch deployed, attackers can access, modify, or delete sensitive guest and operational data, directly threatening business continuity and customer trust.

Business Impact: Severe

Compensating Controls

Deploy WAF rules to detect and block SQL injection patterns in the account_id parameter; implement database-level query monitoring and alerting; restrict network access to /hotel/admin/mod_users/index.php to trusted IP ranges or VPN only; disable the vulnerable endpoint entirely if functionality permits; enforce principle of least privilege for database service accounts; enable database transaction logging for forensic analysis; consider running the application in a containerized sandbox with minimal database permissions.
