CVE-2024-58307
📋 TL;DR
CSZCMS 1.3.0 contains an authenticated SQL injection vulnerability in the members view functionality. Authenticated attackers can inject malicious SQL code through the view parameter to execute time-based blind SQL injection attacks and extract database information. This affects all CSZCMS 1.3.0 installations with authenticated user access.
💻 Affected Systems
- CSZCMS
📦 What is this software?
Csz Cms by Cszcms
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive user data, credentials, and potential remote code execution through database functions.
Likely Case
Data exfiltration of user information, administrative credentials, and potentially sensitive application data.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented.
🎯 Exploit Status
Exploit requires authenticated access but SQL injection is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.cszcms.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the members view functionality.
Modify PHP code to use prepared statements with parameterized queries instead of direct SQL concatenation.
Web Application Firewall Rules
linuxDeploy WAF rules to block SQL injection patterns in the members view endpoint.
Add WAF rule to block SQL keywords in view parameter: modsecurity_rules 'SecRule ARGS:view "(?i:(union|select|insert|update|delete|drop|--|#|\/\*|\*\/|xp_))" "deny,status:403,id:1001"
🧯 If You Can't Patch
- Restrict authenticated user access to minimum required privileges.
- Implement network segmentation to isolate the CSZCMS application from sensitive databases.
🔍 How to Verify
Check if Vulnerable:
Test the members view endpoint with SQL injection payloads in the view parameter while authenticated.Check Version:
Check CSZCMS version in admin panel or configuration files.Verify Fix Applied:
Verify that parameterized queries are implemented and SQL injection attempts are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts followed by members view access
- Long response times from members view endpoint (time-based SQLi)
Network Indicators:
- SQL keywords in HTTP POST/GET parameters to members view endpoint
- Unusual database connection patterns from application server
SIEM Query:
source="web_logs" AND (uri="/members/view" OR uri="/members") AND (param="view" AND value MATCHES "(?i:union|select|insert|update|delete|drop|--|#|\/\*|\*\/|xp_)")
