CVE-2016-15048 in Hotel Broadband Operation System
Summary
by MITRE • 10/22/2025
AMTT Hotel Broadband Operation System (HiBOS) contains an unauthenticated command injection vulnerability in the /manager/radius/server_ping.php endpoint. The application constructs a shell command that includes the user-supplied ip parameter and executes it without proper validation or escaping. An attacker can insert shell metacharacters into the ip parameter to inject and execute arbitrary system commands as the web server user. The initial third-party disclosure in 2016 recommended contacting the vendor for remediation guidance. Additionally, this product may have been rebranded under a different name. VulnCheck has observed this vulnerability being exploited in the wild as of 2025-10-14 at 04:45:53.510819 UTC.

The CVE-2016-15048 vulnerability affects the AMTT Hotel Broadband Operation System HiBOS, a network management solution commonly deployed in hospitality environments for broadband service provisioning. This system serves as a critical component for managing network access and user authentication, making it an attractive target for attackers seeking persistent access to hotel network infrastructures. The vulnerability exists within the /manager/radius/server_ping.php endpoint, which is designed to validate network connectivity to specified IP addresses through ICMP ping operations. The flaw represents a classic command injection vulnerability that stems from inadequate input sanitization and improper command construction practices. The system constructs shell commands by directly incorporating user-supplied parameters without proper validation or escaping mechanisms, creating a pathway for malicious command execution.
The technical exploitation of this vulnerability occurs through the ip parameter within the server_ping.php endpoint where attackers can inject shell metacharacters such as semicolons, ampersands, or pipe characters to extend the original ping command. When the application processes these malicious inputs, it executes arbitrary system commands with the privileges of the web server user, typically running with limited but potentially elevated permissions on the hosting system. This command injection flaw maps directly to CWE-77 and CWE-88 within the Common Weakness Enumeration framework, specifically categorized as a command injection vulnerability that allows arbitrary code execution. The vulnerability's severity is compounded by the fact that it requires no authentication, making it particularly dangerous as any remote attacker can exploit it without prior credentials. The attack vector involves sending specially crafted HTTP requests to the vulnerable endpoint, where the malicious input is processed and executed as part of the underlying shell command construction.
The operational impact of this vulnerability extends beyond simple remote code execution, as it provides attackers with persistent access to hotel network infrastructure and potentially sensitive guest data. The web server user context execution means that attackers can leverage this access to escalate privileges, access network configuration files, or establish backdoors for continued access. Given that this system is deployed in hospitality environments, the attack surface includes guest networks, administrative interfaces, and potentially interconnected systems that may contain additional vulnerabilities. The vulnerability's exploitation in the wild since 2025 demonstrates its continued relevance and the lack of proper remediation by affected organizations, indicating that many deployments remain unpatched despite the known risk. This persistence of exploitation aligns with ATT&CK techniques such as T1059.001 for command and scripting interpreter and T1078.004 for valid accounts, as attackers can leverage the compromised system to maintain access and move laterally within network environments.
Organizations should implement immediate mitigations including input validation and parameter sanitization for all user-supplied inputs, particularly those used in system command construction. The recommended approach involves using secure coding practices that employ proper escaping mechanisms or parameterized command execution rather than direct string concatenation. Network segmentation and access control measures should be implemented to limit access to management interfaces, while regular security audits should verify that no unauthorized modifications have occurred. The vulnerability's persistence in exploitation suggests that organizations should also conduct comprehensive network scans to identify all instances of this software deployment, regardless of branding or version numbers. Additionally, implementing web application firewalls and monitoring for suspicious command execution patterns can help detect and prevent exploitation attempts. The vendor's original disclosure in 2016 should have prompted immediate remediation efforts, but the continued exploitation indicates a failure in vulnerability management processes and underscores the importance of proactive security measures in maintaining network infrastructure integrity.
