💻 Affected Systems
- Jepaas
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, and potential remote code execution on the database server.
Likely Case
Unauthorized data access, data exfiltration, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries in place.
🎯 Exploit Status
SQL injection via orderSQL parameter requires authentication but is straightforward to exploit once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://gitee.com/ketr/jepaas-release/issues/IAPJ8H?from=project-issue
Restart Required: No
Instructions:
No official patch available. Monitor the Gitee repository for updates and apply when available.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to reject malicious SQL characters in orderSQL parameter
Implement regex filter: ^[a-zA-Z0-9_,\s]+$ for orderSQL parameter
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns
Add WAF rule to block requests containing SQL keywords in orderSQL parameter
🧯 If You Can't Patch
- Disable or restrict access to /homePortal/loadUserMsg endpoint
- Implement network segmentation to isolate Jepaas database from other systems
🔍 How to Verify
Check if Vulnerable:
Test the /homePortal/loadUserMsg endpoint with SQL injection payloads in orderSQL parameterCheck Version:
Check Jepaas version in application settings or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by SQL injection patterns
Network Indicators:
- HTTP requests to /homePortal/loadUserMsg with SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="/homePortal/loadUserMsg" AND (param="orderSQL" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "--")
