CVE-2025-1843
📋 TL;DR
This critical SQL injection vulnerability in Mini-Tmall allows remote attackers to execute arbitrary SQL commands by manipulating the 'orderBy' parameter in the ProductMapper.java file. This can lead to data theft, modification, or deletion. All systems running Mini-Tmall up to version 20250211 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, modification, or deletion; potential privilege escalation to execute system commands via database functions.
Likely Case
Unauthorized access to product data, customer information, or administrative credentials stored in the database.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database user privilege restrictions in place.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
1. Contact the vendor for an official patch. 2. If no patch is available, implement parameterized queries in the ProductMapper.java file. 3. Validate and sanitize all user inputs, especially the orderBy parameter. 4. Restart the application after modifications.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation to only allow safe characters in the orderBy parameter
Modify com/xq/tmall/dao/ProductMapper.java to validate orderBy parameter against a whitelist of allowed values
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns in orderBy parameters
Add WAF rule: Detect and block SQL keywords (UNION, SELECT, INSERT, etc.) in orderBy parameter
🧯 If You Can't Patch
- Implement network segmentation to restrict database access from application servers
- Apply principle of least privilege to database user accounts used by the application
🔍 How to Verify
Check if Vulnerable:
Review the ProductMapper.java file for the select function and check if orderBy parameter is used in string concatenation without proper sanitization.Check Version:
Check application version in configuration files or via application interface if availableVerify Fix Applied:
Test the orderBy parameter with SQL injection payloads; successful fix should return error or no data rather than executing SQL.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following SQL injection patterns
- Unexpected database errors in application logs
Network Indicators:
- HTTP requests with SQL keywords in orderBy parameter
- Unusual database traffic patterns from application servers
SIEM Query:
source="web_logs" AND (orderBy CONTAINS "UNION" OR orderBy CONTAINS "SELECT" OR orderBy CONTAINS "INSERT")
