CVE-2024-52724
📋 TL;DR
ZZCMS 2023 contains a SQL injection vulnerability in the /q/show.php endpoint that allows attackers to execute arbitrary SQL commands. This affects all deployments of ZZCMS 2023 that have this endpoint accessible. Attackers could potentially access, modify, or delete database content.
💻 Affected Systems
- ZZCMS
📦 What is this software?
Zzcms by Zzcms
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, or remote code execution via database functions.
Likely Case
Data extraction from the database including user credentials, sensitive information, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status
Proof of concept code is publicly available in GitHub repositories, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: Not available
Restart Required: No
Instructions:
Check for official patches from ZZCMS vendor. If unavailable, implement workarounds or upgrade to a newer secure version.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the /q/show.php endpoint
Modify show.php to use prepared statements: $stmt = $db->prepare('SELECT * FROM table WHERE id = ?'); $stmt->execute([$input]);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests to /q/show.php containing SQL keywords like UNION, SELECT, INSERT, UPDATE, DELETE, DROP, OR, AND with suspicious patterns
🧯 If You Can't Patch
- Restrict access to /q/show.php endpoint using network ACLs or authentication
- Implement database user with minimal privileges (read-only if possible) for the application
🔍 How to Verify
Check if Vulnerable:
Test the /q/show.php endpoint with SQL injection payloads like ' OR '1'='1 or time-based blind SQL payloadsCheck Version:
Check ZZCMS version in admin panel or configuration filesVerify Fix Applied:
Retest with SQL injection payloads after implementing fixes - should return error messages or no data instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed requests to /q/show.php with SQL keywords
- Unexpected database queries from application user
Network Indicators:
- HTTP requests to /q/show.php containing SQL injection patterns
- Unusual database traffic patterns from web server
SIEM Query:
source="web_logs" AND uri="/q/show.php" AND (request CONTAINS "UNION" OR request CONTAINS "SELECT" OR request CONTAINS "OR '1'='1")
