CVE-2025-12253: Amttgroup Hibos SQLi Vulnerability

CVE-2025-12253 Overview

A SQL injection vulnerability has been identified in AMTT Hotel Broadband Operation System (HIBOS) version 1.0. The vulnerability exists in the /user/portal/get_expiredtime.php file, where improper handling of the uid parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or service disruption.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive guest and operational data, modify database contents, or potentially compromise the underlying hotel network infrastructure.

Technical Details for CVE-2025-12253

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the get_expiredtime.php endpoint. The affected PHP script accepts a uid parameter that is directly incorporated into SQL queries without proper sanitization or parameterized query implementation. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws.

The attack can be initiated remotely over the network without requiring authentication or user interaction, making it accessible to any attacker who can reach the vulnerable endpoint. Successful exploitation could result in unauthorized data access, data modification, or availability impacts to the hotel management system.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries in the PHP application. The uid parameter is passed directly into database queries without proper sanitization, escaping, or use of prepared statements. This allows attackers to break out of the intended SQL query structure and execute arbitrary SQL commands.

Attack Vector

The vulnerability is exploitable via network-based attacks targeting the /user/portal/get_expiredtime.php endpoint. An attacker can craft malicious requests containing SQL injection payloads in the uid parameter. Since the exploit has been publicly disclosed, attackers have access to information about how to target this vulnerability. The vendor was contacted about this issue but did not respond, leaving systems potentially unpatched.

The attack does not require authentication or any special privileges, significantly lowering the barrier for exploitation. Attackers could leverage this vulnerability to extract sensitive hotel guest information, billing data, network credentials, or other sensitive information stored in the database.

Detection Methods for CVE-2025-12253

Indicators of Compromise

• HTTP requests to /user/portal/get_expiredtime.php containing SQL injection patterns in the uid parameter
• Database query errors or unexpected SQL syntax in application logs
• Unusual database queries or data access patterns targeting user or session tables
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection attempts in the uid parameter
• Monitor web server access logs for suspicious requests to get_expiredtime.php with encoded or malformed input
• Implement database activity monitoring to detect unusual query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) to alert on known SQL injection attack signatures

Monitoring Recommendations

• Enable detailed logging for the /user/portal/ directory and review logs for injection attempts
• Set up alerts for database errors related to SQL syntax that may indicate exploitation attempts
• Monitor for bulk data extraction patterns that could indicate successful SQL injection exploitation
• Review database audit logs for unauthorized SELECT, UPDATE, or DELETE operations

How to Mitigate CVE-2025-12253

Immediate Actions Required

• Restrict network access to the vulnerable /user/portal/get_expiredtime.php endpoint using firewall rules or access control lists
• Deploy WAF rules specifically targeting SQL injection in the uid parameter
• Consider disabling the affected functionality until a patch is available
• Implement network segmentation to limit potential lateral movement if the system is compromised

Patch Information

No official patch is currently available from AMTT Group. The vendor was contacted regarding this disclosure but did not respond. Organizations using HIBOS should implement compensating controls and monitor for any vendor updates. For additional technical details, refer to the GitHub Issue Discussion and VulDB advisory.

Workarounds

• Implement input validation at the web server or reverse proxy level to sanitize the uid parameter before it reaches the application
• Deploy a Web Application Firewall (WAF) with SQL injection detection capabilities in front of the HIBOS application
• Restrict access to the /user/portal/ directory to trusted IP addresses only
• If possible, modify the PHP code to use prepared statements or parameterized queries for database interactions

# Example: Block access to vulnerable endpoint using Apache .htaccess
<Files "get_expiredtime.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
