CVE-2026-15494: AMTT Hotel Broadband SQLi Vulnerability

CVE-2026-15494 Overview

CVE-2026-15494 is a SQL injection vulnerability in AMTT Hotel Broadband Operation System 1.0. The flaw resides in the manager/network/switch_status.php script, where the ID parameter is passed to a backend database query without proper sanitization. Remote attackers holding valid high-privilege credentials can manipulate the parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed, and the vendor did not respond to disclosure attempts. The weakness is tracked under [CWE-74] (Improper Neutralization of Special Elements in Output).

Critical Impact
Authenticated remote attackers can inject SQL through the ID parameter of switch_status.php, potentially disclosing or altering data managed by the hotel broadband platform.

Technical Details for CVE-2026-15494

Vulnerability Analysis

The vulnerability affects the switch_status.php endpoint inside the manager/network/ directory of the AMTT Hotel Broadband Operation System. The script accepts an ID argument supplied by the client and incorporates it into a SQL query without proper neutralization of special characters. This allows an attacker to alter the query's structure and execute unintended database statements.

Exploitation requires network access to the management interface and high-privilege credentials, according to the reported CVSS vector. Once authenticated, the attacker can leverage the injection to enumerate tables, read stored records, or modify database contents. The vendor was notified but did not respond, and no official patch has been announced. Public exploit details are available through the referenced GitHub issue tracker and VulDB entry.

Root Cause

The root cause is improper input neutralization in the query construction path of switch_status.php. The ID argument is concatenated into the SQL statement rather than bound as a parameter. This design flaw maps to [CWE-74] and enables classic in-band SQL injection payloads to be processed by the database engine.

Attack Vector

The attack vector is network-based. An authenticated user with access to the management console sends a crafted HTTP request to manager/network/switch_status.php, supplying a malicious ID value. The backend passes the tainted value into the SQL query, and the database executes the attacker-controlled clauses. No user interaction is required beyond the attacker's own request.

Because exploit code has been published, defenders should assume opportunistic scanning against exposed installations. Technical details are documented in the VulDB vulnerability record.

Detection Methods for CVE-2026-15494

Indicators of Compromise

HTTP requests to manager/network/switch_status.php containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP, or comment sequences in the ID parameter.
Unexpected database errors or long response times originating from the switch_status.php endpoint.
Access to the manager/network/ path from source IP addresses outside the expected administrative network.

Detection Strategies

Deploy web application firewall rules that inspect the ID parameter on switch_status.php for SQL injection patterns and block anomalous payloads.
Enable verbose query logging on the backend database and alert on syntactically malformed queries referencing the switch status table.
Correlate authentication logs with subsequent requests to manager/network/switch_status.php to identify credential misuse.

Monitoring Recommendations

Baseline normal ID parameter values (typically numeric) and alert on non-numeric or oversized inputs.
Monitor for outbound database connections and data volumes that exceed operational norms.
Retain HTTP access logs for the management interface and review them for repeated 500-series errors tied to switch_status.php.

How to Mitigate CVE-2026-15494

Immediate Actions Required

Restrict network access to the AMTT Hotel Broadband management interface using firewall or VPN controls so only trusted administrators can reach it.
Rotate credentials for all high-privilege accounts and enforce strong, unique passwords to reduce the risk of authenticated exploitation.
Deploy a web application firewall rule that blocks SQL metacharacters in the ID parameter of manager/network/switch_status.php.

Patch Information

No vendor patch is available. According to the disclosure, the vendor was contacted but did not respond. Operators should track updates on the VulDB entry for CVE-2026-15494 and the public issue tracker for any future remediation guidance.

Workarounds

Place the management console behind a reverse proxy that enforces parameter allow-lists, permitting only numeric values for ID.
Disable or remove the switch_status.php endpoint if it is not required for daily operations.
Apply database-level least privilege so the account used by the web application cannot read or write outside required tables.

bash

# Example WAF rule (ModSecurity) restricting the ID parameter to digits only
SecRule REQUEST_URI "@contains /manager/network/switch_status.php" \
    "chain,phase:2,deny,status:403,id:1015494,\
    msg:'Blocked non-numeric ID on switch_status.php (CVE-2026-15494)'"
    SecRule ARGS:ID "!@rx ^[0-9]+$" "t:none"
