⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive business data, financial records, and user credentials leading to data destruction, financial fraud, and system takeover.
Likely Case
Unauthorized access to business data, extraction of sensitive information, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
SQL injection vulnerabilities are well-understood and frequently weaponized. The specific bypass technique may require some understanding of jshERP's protection mechanisms.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://github.com/jishenghua/jshERP/issues/99
Restart Required: No
Instructions:
1. Monitor the jshERP GitHub repository for patches. 2. Apply any available security updates immediately. 3. Consider upgrading to a newer version if available.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement strict input validation for the findallocationDetail() function parameters
Modify com.jsh.erp.controller.DepotHeadController to validate all user inputs before processing
WAF Deployment
allDeploy a Web Application Firewall with SQL injection protection rules
Configure WAF to block SQL injection patterns in requests to /depotHead/findallocationDetail
🧯 If You Can't Patch
- Implement network segmentation to isolate the jshERP database from other systems
- Enable detailed logging and monitoring for SQL injection attempts on the affected endpoint
🔍 How to Verify
Check if Vulnerable:
Review the com.jsh.erp.controller.DepotHeadController source code for proper parameterized queries in findallocationDetail() functionCheck Version:
Check the jshERP version in the application configuration or about pageVerify Fix Applied:
Test the findallocationDetail() endpoint with SQL injection payloads to confirm they are properly rejected📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from the jshERP application
- Multiple failed login attempts followed by SQL error messages
- Requests to /depotHead/findallocationDetail with SQL keywords
Network Indicators:
- Unusual database connection patterns from the application server
- Large data transfers from the database server
SIEM Query:
source="jshERP" AND (url="/depotHead/findallocationDetail" AND (request CONTAINS "UNION" OR request CONTAINS "SELECT" OR request CONTAINS "INSERT" OR request CONTAINS "DELETE"))
