CVE-2026-4288 Overview
A SQL injection vulnerability has been identified in Tiandy Easy7 Integrated Management Platform version 7.17.0. The vulnerability exists in an unknown function of the file /rest/devStatus/getDevDetailedInfo within the Endpoint component. By manipulating the ID argument, an attacker can inject malicious SQL commands. This vulnerability can be exploited remotely without authentication, and a public exploit has been made available, increasing the risk of active exploitation.
Critical Impact
Unauthenticated remote attackers can exploit this SQL injection vulnerability to potentially extract, modify, or delete sensitive data from the database, compromise system integrity, and gain unauthorized access to the management platform.

Technical Details for CVE-2026-4288
Vulnerability Analysis
This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the /rest/devStatus/getDevDetailedInfo endpoint in the Tiandy Easy7 Integrated Management Platform. The vulnerability stems from improper handling of the ID parameter, which allows attackers to inject arbitrary SQL statements into database queries.
The attack can be launched remotely over the network without requiring authentication or user interaction. An exploit has been publicly disclosed, making this vulnerability particularly concerning for organizations running affected versions of the platform. The vendor was contacted about this disclosure but did not respond.
Root Cause
The root cause of this vulnerability is insufficient input validation and lack of proper parameterized queries in the /rest/devStatus/getDevDetailedInfo endpoint. The application directly incorporates user-supplied input from the ID argument into SQL queries without adequate sanitization, enabling SQL injection attacks.
Attack Vector
The vulnerability is exploitable via network-based attacks targeting the REST API endpoint. An attacker can craft malicious HTTP requests to the /rest/devStatus/getDevDetailedInfo endpoint with specially crafted ID parameter values containing SQL injection payloads.
The attack does not require authentication, making it accessible to any network-level attacker who can reach the management platform. The injected SQL commands can be used to bypass authentication, extract sensitive data, modify database contents, or potentially execute administrative operations on the underlying database system.
Technical details and proof-of-concept information are available in the Feishu Document Link and VulDB entry #351293.
Detection Methods for CVE-2026-4288
Indicators of Compromise
- Unusual or malformed HTTP requests to /rest/devStatus/getDevDetailedInfo containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
- Database error messages or unexpected responses from the affected endpoint
- Anomalous database queries in logs containing UNION, SELECT, INSERT, UPDATE, DELETE, or DROP statements originating from web application context
- Increased database query execution times indicating time-based blind SQL injection attempts
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /rest/devStatus/getDevDetailedInfo
- Implement application-level logging to capture all requests to the vulnerable endpoint with full parameter details
- Configure database activity monitoring to alert on suspicious query patterns or unauthorized data access
- Use intrusion detection systems (IDS) with SQL injection signature detection capabilities
Monitoring Recommendations
- Monitor HTTP access logs for requests containing SQL metacharacters targeting the /rest/devStatus/getDevDetailedInfo endpoint
- Enable database audit logging to track queries executed against sensitive tables
- Set up alerts for failed database query attempts or syntax errors that may indicate exploitation attempts
- Review network traffic for suspicious patterns targeting the Tiandy Easy7 management platform
How to Mitigate CVE-2026-4288
Immediate Actions Required
- Restrict network access to the Tiandy Easy7 Integrated Management Platform to trusted IP addresses only
- Place a Web Application Firewall (WAF) in front of the application to filter SQL injection attempts
- Monitor the vulnerable endpoint /rest/devStatus/getDevDetailedInfo for suspicious activity
- Consider disabling or blocking access to the affected endpoint if not critical for operations
Patch Information
No official patch is currently available from the vendor. According to the vulnerability disclosure, the vendor was contacted about this issue but did not respond. Organizations should monitor for vendor updates and apply patches as soon as they become available.
For additional details, refer to VulDB #351293 and VulDB Submission #771963.
Workarounds
- Implement network segmentation to isolate the management platform from untrusted networks
- Deploy a reverse proxy with SQL injection filtering capabilities in front of the application
- Use firewall rules to restrict access to the vulnerable endpoint to only necessary internal systems
- Consider implementing application-level input validation through a middleware proxy if direct patching is not possible
# Example: Block access to vulnerable endpoint using iptables (adjust IP ranges as needed)
# Allow only trusted management subnet to access the platform
iptables -A INPUT -p tcp --dport 80 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
