⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, or potential remote code execution if database permissions allow.
Likely Case
Unauthorized access to comment data, user information, or other database tables accessible to the application's database user.
If Mitigated
Limited impact if database user has minimal permissions and proper input validation is enforced at other layers.
🎯 Exploit Status
Exploit details are publicly available in GitHub repository. Requires authentication to admin panel (/index.php/admins/).
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None
Restart Required: No
Instructions:
No official patch available. Vendor did not respond to disclosure. Consider upgrading if vendor releases fix, or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameter validation to filter SQL injection attempts in the deleteAll/findAll/delete functions
Modify /index.php/admins/Comment/deleteAll.html to validate 'data' parameter using prepared statements or strict type checking
WAF Rule
allImplement web application firewall rules to block SQL injection patterns
Add WAF rule: Detect and block SQL keywords in POST parameters to /index.php/admins/Comment/deleteAll.html
🧯 If You Can't Patch
- Restrict access to admin panel using IP whitelisting or VPN
- Implement database user with minimal required permissions (read-only where possible)
🔍 How to Verify
Check if Vulnerable:
Check if JIZHICMS version is ≤2.5.5 and review /index.php/admins/Comment/deleteAll.html for lack of parameter validationCheck Version:
Check JIZHICMS configuration files or admin panel for version informationVerify Fix Applied:
Test the deleteAll functionality with SQL injection payloads to confirm they are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple DELETE/SELECT queries from single admin session
- Requests to /index.php/admins/Comment/deleteAll.html with suspicious parameters
Network Indicators:
- POST requests to vulnerable endpoint containing SQL keywords (UNION, SELECT, DELETE, etc.)
SIEM Query:
source="web_logs" AND uri="/index.php/admins/Comment/deleteAll.html" AND (param="data" CONTAINS "UNION" OR param="data" CONTAINS "SELECT" OR param="data" CONTAINS "DELETE")
