CVE-2025-13123: Amttgroup Hibos SQLi Vulnerability

CVE-2025-13123 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_firstdate.php file, where improper handling of the uid parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely by authenticated users to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers with low privileges can exploit this SQL injection vulnerability to access sensitive hotel guest data, manipulate booking records, or potentially compromise the entire database backend of the hotel broadband management system.

Affected Products

• AMTT Hotel Broadband Operation System (HIBOS) 1.0
• amttgroup hibos

Technical Details for CVE-2025-13123

Vulnerability Analysis

This SQL injection vulnerability (classified under CWE-89 and CWE-74) affects the AMTT Hotel Broadband Operation System's user portal functionality. The vulnerable endpoint /user/portal/get_firstdate.php fails to properly sanitize or parameterize the uid argument before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed by the database server with the application's privileges.

The vulnerability can be exploited remotely over the network and requires only low-level authentication. Due to the nature of hotel management systems, successful exploitation could expose sensitive guest information including personal details, room assignments, billing data, and network usage records.

Root Cause

The root cause is inadequate input validation and the use of unsanitized user input in SQL query construction. The uid parameter is directly concatenated or interpolated into SQL statements without proper escaping, prepared statements, or parameterized queries. This violates secure coding practices for database interaction and allows attackers to break out of the intended query structure.

Attack Vector

The attack can be launched remotely over the network by sending crafted HTTP requests to the vulnerable PHP endpoint. An authenticated attacker can manipulate the uid parameter value to include SQL syntax that modifies the query's logic. The exploit has been publicly disclosed, increasing the risk of widespread exploitation. The vendor was contacted about this vulnerability but did not respond, leaving systems potentially unpatched.

The vulnerability mechanism involves injecting SQL metacharacters and commands through the uid parameter in requests to /user/portal/get_firstdate.php. Attackers can craft payloads that extract database contents, bypass authentication checks, modify records, or potentially execute administrative database commands. For technical details regarding the vulnerability, refer to the GitHub CVE Issue Discussion and VulDB entry #332351.

Detection Methods for CVE-2025-13123

Indicators of Compromise

• HTTP requests to /user/portal/get_firstdate.php containing SQL syntax characters such as single quotes, double dashes, UNION keywords, or encoded variants in the uid parameter
• Unusual database query patterns or errors in application logs indicating SQL syntax errors
• Unexpected data extraction or exfiltration from the hotel management database
• Access attempts to sensitive tables containing guest information or credentials

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to the HIBOS application
• Monitor web server access logs for suspicious requests containing SQL injection payloads targeting /user/portal/get_firstdate.php
• Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for the HIBOS application and database backend to capture all requests and query executions
• Set up alerts for database errors or exceptions that may indicate injection attempts
• Monitor network traffic for unusual data volumes being transferred from the database server
• Review authentication logs for any signs of privilege escalation following exploitation attempts

How to Mitigate CVE-2025-13123

Immediate Actions Required

• Restrict network access to the HIBOS application to trusted IP ranges only
• Implement Web Application Firewall rules to filter SQL injection patterns in the uid parameter
• Consider temporarily disabling the /user/portal/get_firstdate.php endpoint if not critical for operations
• Audit database access logs to identify any potential exploitation that may have already occurred
• Apply principle of least privilege to database accounts used by the application

Patch Information

No official patch is currently available from the vendor. According to the CVE disclosure, the vendor (AMTT Group) was contacted about this vulnerability but did not respond. Organizations using HIBOS should implement compensating controls and consider migrating to alternative hotel broadband management solutions until a patch is released. Monitor VulDB #332351 for updates on vendor response.

Workarounds

• Implement input validation at the web server level using ModSecurity or similar WAF solutions to filter malicious SQL characters from the uid parameter
• Deploy a reverse proxy with SQL injection filtering capabilities in front of the HIBOS application
• Use database-level prepared statement enforcement if the database server supports it
• Restrict database user permissions to minimum required operations and prevent administrative commands
• Consider implementing a custom PHP wrapper to sanitize the uid parameter before it reaches the vulnerable code
