CVE-2024-39072 identifies an SQL injection vulnerability in the AMTT Hotel Broadband Operation System (HiBOS) version 3.0.3.151204, specifically within the manager/conference/calendar_remind.php script. SQL injection (CWE-89) occurs when untrusted input is improperly sanitized before being included in SQL queries, allowing attackers to manipulate backend database commands. In this case, the vulnerability requires an authenticated user with some privileges (PR:L) and user interaction (UI:R) to exploit. The attacker can potentially execute arbitrary SQL commands, which may lead to unauthorized data access, modification, or deletion, impacting confidentiality, integrity, and availability. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L) indicates network attack vector, low attack complexity, required privileges, and user interaction, with partial impacts on all three security properties. No patches or public exploits are currently available, but the vulnerability is published and should be addressed promptly. The affected system is used in hotel broadband operations, likely managing conference scheduling and reminders, making it a critical component for hospitality service continuity. The vulnerability underscores the importance of secure input handling in web applications, especially in specialized operational environments.

The vulnerability could allow an authenticated attacker to perform SQL injection attacks, leading to unauthorized access or modification of sensitive data within the hotel broadband operation system. This could result in data leakage of customer or operational information, manipulation of conference schedules or reminders, and potential disruption of service availability. Such impacts could degrade customer trust, cause operational downtime, and expose organizations to regulatory or compliance risks. Given the hospitality sector's reliance on continuous broadband and scheduling services, exploitation could disrupt guest services and internal operations. Although exploitation requires user privileges and interaction, insider threats or compromised accounts could leverage this flaw. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often target hospitality infrastructure. Organizations worldwide using HiBOS or similar systems face risks to data integrity and service reliability.

To mitigate this vulnerability, organizations should first verify if they are running the affected version of AMTT HiBOS (v3.0.3.151204) and monitor vendor communications for patches or updates. In the absence of official patches, implement strict input validation and sanitization on all user-supplied data, especially in the calendar_remind.php component. Employ parameterized queries or prepared statements to prevent SQL injection. Restrict access to the vulnerable interface to only trusted and necessary users, applying the principle of least privilege. Monitor database logs and application behavior for unusual queries or anomalies indicative of injection attempts. Conduct regular security assessments and code reviews focusing on input handling. Additionally, consider deploying web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this endpoint. Educate users with access about the risks of phishing or social engineering that could lead to privilege misuse. Finally, maintain comprehensive backups to enable recovery in case of data tampering or loss.
