⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, or full system takeover through SQL injection to RCE chaining.
Likely Case
Database information disclosure, data manipulation, or potential privilege escalation through SQL injection.
If Mitigated
Limited impact if proper input validation, WAF rules, and network segmentation are in place.
🎯 Exploit Status
Exploit details are publicly available on GitHub and vuldb.com. The vulnerability requires manipulation of the 'folderid' parameter in HTTP GET requests.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available - vendor did not respond to disclosure
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
WAF Rule Implementation
allImplement Web Application Firewall rules to block SQL injection patterns in the 'folderid' parameter
Depends on specific WAF platform - create rule to detect SQL patterns in folderid parameter
Input Validation Filter
allAdd input validation to sanitize the folderid parameter before processing
Implementation specific to application code - validate folderid contains only expected characters
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the KSOA application
- Deploy intrusion detection systems to monitor for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test by sending SQL injection payloads to /kmf/folder.jsp?folderid=[SQL_PAYLOAD] and observing database errors or unexpected responsesCheck Version:
Check Yonyou KSOA version through application interface or configuration filesVerify Fix Applied:
Test with SQL injection payloads after implementing fixes - should receive proper error handling or rejection📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in folderid parameter values
- Database error messages in application logs
- Multiple failed parameter manipulation attempts
Network Indicators:
- HTTP GET requests to /kmf/folder.jsp with SQL keywords in parameters
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND uri="/kmf/folder.jsp" AND (param="folderid" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "' OR '")
