CVE-2024-28714
📋 TL;DR
This SQL injection vulnerability in CRMEB_Java e-commerce system allows attackers to execute arbitrary SQL commands via the groupid parameter. Attackers can potentially read, modify, or delete database contents, and in some configurations execute arbitrary code. All deployments of CRMEB_Java version 1.3.4 are affected.
💻 Affected Systems
- CRMEB_Java e-commerce system
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise including database destruction, sensitive data theft, and remote code execution leading to full server takeover.
Likely Case
Database information disclosure, data manipulation, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or minor data exposure.
🎯 Exploit Status
SQL injection via groupid parameter is straightforward to exploit. Public proof-of-concept exists in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: http://crmebjava.com
Restart Required: No
Instructions:
1. Check vendor website for patches or updated versions. 2. If no patch available, implement input validation and parameterized queries. 3. Consider upgrading to a newer version if available.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to reject malicious groupid parameter values
Implement regex validation: ^[0-9]+$ for groupid parameter
Web Application Firewall Rules
allBlock SQL injection patterns in groupid parameter
WAF rule: Detect SQL keywords in groupid parameter
🧯 If You Can't Patch
- Implement parameterized queries/prepared statements for all database operations
- Apply strict input validation and sanitization for the groupid parameter
🔍 How to Verify
Check if Vulnerable:
Test groupid parameter with SQL injection payloads like: groupid=1' OR '1'='1
Check Version:
Check application version in admin panel or configuration files
Verify Fix Applied:
Test with same payloads and verify no SQL errors or unexpected behavior occurs
📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Unusual database queries from web application
- Multiple failed login attempts following SQL errors
Network Indicators:
- HTTP requests with SQL keywords in groupid parameter
- Abnormal database connection patterns from web server
SIEM Query:
source="web_logs" AND (groupid="*' OR*" OR groupid="*UNION*" OR groupid="*SELECT*" OR groupid="*--*")
