⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover via SQL injection to RCE chaining
Likely Case
Unauthorized database access allowing data exfiltration, privilege escalation, or application compromise
If Mitigated
Limited impact with proper input validation, WAF protection, and network segmentation in place
🎯 Exploit Status
Exploit code is publicly available on GitHub, making this easily weaponizable by attackers with basic skills
🛠️ 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
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the /kmf/select.jsp endpoint and folderid parameter
# Example ModSecurity rule: SecRule ARGS:folderid "@detectSQLi" "id:1001,phase:2,deny,status:403"
URL Rewrite/Blocking
allBlock access to the vulnerable endpoint using web server configuration or network filtering
# Apache: RewriteRule ^/kmf/select\.jsp$ - [F]
# Nginx: location ~ ^/kmf/select\.jsp$ { return 403; }
# IIS: Add request filtering rule for /kmf/select.jsp
🧯 If You Can't Patch
- Implement network segmentation to restrict access to Yonyou KSOA systems only to authorized users
- Deploy database monitoring and alerting for unusual SQL queries or access patterns
🔍 How to Verify
Check if Vulnerable:
Test the /kmf/select.jsp endpoint with SQL injection payloads in the folderid parameter (e.g., folderid=1' OR '1'='1)Check Version:
Check Yonyou KSOA version through application interface or configuration filesVerify Fix Applied:
Verify that SQL injection attempts against /kmf/select.jsp are blocked or return error responses📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests to /kmf/select.jsp with special characters in parameters
- Database error logs showing injection attempts
Network Indicators:
- HTTP GET requests to /kmf/select.jsp containing SQL keywords (UNION, SELECT, INSERT, etc.) in parameters
- Unusual database connection patterns from application servers
SIEM Query:
source="web_logs" AND uri_path="/kmf/select.jsp" AND (query_string="*folderid=*'*" OR query_string="*folderid=*%27*")
