CVE-2026-4232: Tiandy Management Platform SQL Injection

CVE-2026-4232 Overview

A SQL Injection vulnerability has been identified in Tiandy Integrated Management Platform version 7.17.0. The vulnerability exists in the /rest/user/getAuthorityByUserId endpoint, where improper handling of the userId parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion. The exploit has been publicly disclosed, and the vendor was contacted but did not respond to the disclosure.

Critical Impact

Remote SQL Injection vulnerability allows unauthenticated attackers to manipulate database queries through the userId parameter, potentially compromising sensitive user authority data and system integrity.

Technical Details for CVE-2026-4232

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the user authority retrieval functionality in Tiandy Integrated Management Platform. The vulnerable endpoint /rest/user/getAuthorityByUserId fails to properly sanitize the userId parameter before incorporating it into SQL queries. This allows an attacker to craft malicious input that alters the intended SQL logic, enabling unauthorized database operations.

The vulnerability is exploitable remotely without authentication, meaning any attacker with network access to the affected system can attempt exploitation. Given that this endpoint handles user authority information, successful exploitation could reveal user permissions, role assignments, and potentially administrative access levels stored in the backend database.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries in the /rest/user/getAuthorityByUserId endpoint. The userId argument is directly concatenated or interpolated into SQL statements without proper sanitization or use of prepared statements. This allows special SQL characters and commands passed through the userId parameter to be interpreted as part of the SQL query rather than as data, enabling SQL Injection attacks.

Attack Vector

The attack can be launched remotely over the network. An attacker sends a crafted HTTP request to the /rest/user/getAuthorityByUserId endpoint with a malicious userId parameter containing SQL injection payloads. The vulnerable application processes this input without proper sanitization, executing the injected SQL commands against the backend database.

Typical exploitation scenarios include:

The attacker crafts a request to the vulnerable REST endpoint, manipulating the userId parameter to include SQL metacharacters and injection payloads. For example, injecting Boolean-based or time-based blind SQL injection payloads can allow data extraction, while UNION-based injection can expose data from other database tables. Depending on database permissions, attackers may also be able to modify or delete records, or potentially execute operating system commands if the database supports such functionality.

For detailed technical information about this vulnerability, see the VulDB entry #351155 or the disclosure documentation.

Detection Methods for CVE-2026-4232

Indicators of Compromise

• Unusual or malformed requests to /rest/user/getAuthorityByUserId containing SQL syntax such as single quotes, semicolons, UNION, SELECT, or -- comment sequences
• Database error messages appearing in HTTP responses from the affected endpoint
• Unexpected database query patterns or increased query execution times indicating time-based blind injection attempts
• Unauthorized data access or modifications in user authority tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the userId parameter
• Enable detailed logging for the /rest/user/getAuthorityByUserId endpoint and monitor for suspicious parameter values
• Deploy database activity monitoring to identify anomalous SQL queries originating from the application
• Utilize SentinelOne Singularity XDR to correlate web server logs with database activity for comprehensive threat detection

Monitoring Recommendations

• Monitor HTTP access logs for requests to /rest/user/getAuthorityByUserId with encoded or obfuscated SQL injection payloads
• Set up alerts for database errors or exceptions triggered by the Tiandy Management Platform application
• Review authentication and authorization logs for any unauthorized privilege changes that may indicate successful exploitation
• Implement network segmentation monitoring to detect lateral movement attempts following potential database compromise

How to Mitigate CVE-2026-4232

Immediate Actions Required

• Restrict network access to the Tiandy Integrated Management Platform to trusted IP addresses only using firewall rules
• Implement a Web Application Firewall (WAF) with SQL injection detection rules for the /rest/user/getAuthorityByUserId endpoint
• Review database permissions and ensure the application uses a least-privilege database account
• Enable comprehensive logging for the affected endpoint and monitor for exploitation attempts

Patch Information

As of the last update on 2026-03-16, the vendor (Tiandy) has not responded to the vulnerability disclosure and no official patch is available. Organizations using the affected Tiandy Integrated Management Platform version 7.17.0 should implement the recommended workarounds and monitor for any vendor security updates. Refer to the VulDB submission #771216 for the latest status information.

Workarounds

• Deploy a reverse proxy or Web Application Firewall (WAF) in front of the application to filter malicious SQL injection payloads
• Implement network-level access controls to restrict access to the vulnerable endpoint to authorized users only
• Consider disabling or restricting access to the /rest/user/getAuthorityByUserId endpoint if not critical to operations
• Segment the database server from the web application server to limit blast radius in case of successful exploitation
