💻 Affected Systems
- kkcms
📦 What is this software?
Kkcms by Kkcms Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation, or remote code execution via database functions.
Likely Case
Unauthorized data access, modification of database content, or authentication bypass.
If Mitigated
Limited impact with proper input validation and parameterized queries in place.
🎯 Exploit Status
SQL injection via URL parameters is well-understood and easily automated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Check for updated versions beyond v1.3.7. 2. If no patch exists, implement parameterized queries in /template/wapian/vlist.php. 3. Validate and sanitize all user inputs, especially the cid parameter.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd input validation to ensure cid parameter contains only expected values.
Modify /template/wapian/vlist.php to validate cid parameter using PHP filter functions
Web Application Firewall (WAF)
allDeploy a WAF to block SQL injection attempts targeting the vulnerable endpoint.
Configure WAF rules to block SQL injection patterns in requests to /template/wapian/vlist.php
🧯 If You Can't Patch
- Restrict network access to the kkcms instance using firewall rules.
- Implement strict input validation and use parameterized queries in the vulnerable file.
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted SQL injection payload to /template/wapian/vlist.php?cid=1' OR '1'='1Check Version:
Check kkcms version in configuration files or admin panel.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and that parameterized queries are implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple requests to /template/wapian/vlist.php with suspicious cid parameters
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in the cid parameter
SIEM Query:
source="web_server" AND uri="/template/wapian/vlist.php" AND (cid="*'*" OR cid="*%27*" OR cid="*SELECT*" OR cid="*UNION*")
