CVE-2026-4287: Tiandy Easy7 Platform SQL Injection Flaw

CVE-2026-4287 Overview

A SQL injection vulnerability has been discovered in Tiandy Easy7 Integrated Management Platform version 7.17.0. The vulnerability exists in an unknown function within the /rest/devStatus/queryResources endpoint. By manipulating the areaId parameter, an attacker can inject malicious SQL commands. This attack can be executed remotely without authentication, and exploit code has been publicly released, increasing the risk of active exploitation.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to potentially access, modify, or delete sensitive database contents in the Tiandy Easy7 Integrated Management Platform without authentication.

Affected Products

• Tiandy Easy7 Integrated Management Platform 7.17.0

Technical Details for CVE-2026-4287

Vulnerability Analysis

This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws including SQL injection. The affected endpoint /rest/devStatus/queryResources fails to properly sanitize the areaId parameter before incorporating it into SQL queries executed against the backend database.

The vulnerability is remotely exploitable and requires no authentication or user interaction, making it particularly dangerous for internet-facing deployments of the Tiandy Easy7 platform. The exploit has been publicly disclosed, which significantly increases the likelihood of real-world attacks against vulnerable systems. The vendor was contacted regarding this vulnerability but did not respond, leaving users without an official patch.

Root Cause

The root cause of this vulnerability is improper input validation and sanitization of the areaId parameter in the /rest/devStatus/queryResources endpoint. The application directly incorporates user-supplied input into SQL queries without adequate neutralization of special characters or use of parameterized queries. This allows attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack vector is network-based, allowing remote exploitation. An attacker can craft malicious HTTP requests to the /rest/devStatus/queryResources endpoint with a specially crafted areaId parameter containing SQL injection payloads. Since no authentication is required, any network-accessible instance of the vulnerable platform is at risk.

The exploitation process typically involves:

1. Identifying an accessible Tiandy Easy7 Integrated Management Platform instance running version 7.17.0
2. Sending HTTP requests to the /rest/devStatus/queryResources endpoint with SQL injection payloads in the areaId parameter
3. Extracting sensitive data from the database or performing unauthorized modifications depending on the attacker's objectives

For technical details on the exploitation methodology, refer to the Feishu Document Resource and VulDB entry #351292.

Detection Methods for CVE-2026-4287

Indicators of Compromise

• Unusual or malformed HTTP requests to the /rest/devStatus/queryResources endpoint containing SQL syntax characters such as single quotes, semicolons, or UNION statements
• Database error messages in application logs indicating SQL syntax errors or unexpected query behavior
• Unexpected database queries or data access patterns in database audit logs
• Anomalous network traffic patterns to the Tiandy Easy7 management interface from unknown or suspicious IP addresses

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the areaId parameter
• Monitor HTTP access logs for requests to /rest/devStatus/queryResources with suspicious parameter values
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attacks
• Enable database query logging and alert on queries containing injection patterns or unauthorized data access

Monitoring Recommendations

• Continuously monitor network traffic to and from Tiandy Easy7 platform instances for anomalous activity
• Set up alerts for multiple failed or malformed requests to the vulnerable endpoint from the same source
• Review database audit logs regularly for signs of data exfiltration or unauthorized modifications
• Implement real-time log analysis using SIEM solutions to correlate suspicious activity across application and database layers

How to Mitigate CVE-2026-4287

Immediate Actions Required

• Restrict network access to the Tiandy Easy7 Integrated Management Platform to trusted IP addresses only using firewall rules
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the vulnerable application
• Consider taking the vulnerable endpoint offline if it is not critical for operations until a patch is available
• Monitor systems closely for signs of exploitation attempts or compromise

Patch Information

No official patch is currently available from the vendor. According to vulnerability reports, Tiandy was contacted regarding this security issue but did not respond. Organizations using the affected platform should implement the recommended workarounds and monitor for vendor security updates.

For additional technical details, refer to the VulDB entry #351292 and the VulDB submission #771956.

Workarounds

• Implement network segmentation to isolate Tiandy Easy7 platform instances from untrusted networks
• Use a reverse proxy or WAF to filter requests containing SQL injection patterns before they reach the application
• If possible, disable or restrict access to the /rest/devStatus/queryResources endpoint through application or web server configuration
• Implement strict input validation at the network edge using custom firewall rules to block requests with suspicious areaId values

# Example: iptables rules to restrict access to the vulnerable platform
# Allow access only from trusted management network
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
