CVE-2022-27126
📋 TL;DR
CVE-2022-27126 is a SQL injection vulnerability in zbzcms v1.0 that allows attackers to execute arbitrary SQL commands via the art parameter at /include/make.php. This affects all installations of zbzcms v1.0, potentially allowing unauthorized access to the database. Attackers could steal, modify, or delete sensitive data stored in the CMS database.
💻 Affected Systems
- zbzcms
📦 What is this software?
Zbzcms by Zbzcms
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the database leading to data theft, data destruction, or full system takeover if database privileges allow command execution.
Likely Case
Unauthorized data access and extraction of sensitive information like user credentials, personal data, or administrative details.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
The vulnerability requires no authentication and has publicly available proof-of-concept details. SQL injection is a well-understood attack vector with many automated tools available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds and code fixes manually.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement proper input validation and parameterized queries for the art parameter in /include/make.php
Modify /include/make.php to use prepared statements with parameterized queries instead of direct SQL concatenation
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules
Configure WAF to block SQL injection patterns in URL parameters
🧯 If You Can't Patch
- Isolate the zbzcms instance behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the web server
🔍 How to Verify
Check if Vulnerable:
Check if /include/make.php exists and contains unsanitized art parameter usage. Test with SQL injection payloads like ' OR '1'='1 in the art parameter.Check Version:
Check CMS version in configuration files or admin panel. Look for zbzcms version 1.0 in code comments or configuration.Verify Fix Applied:
Verify that /include/make.php now uses parameterized queries and properly validates/sanitizes the art parameter input.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple requests to /include/make.php with suspicious art parameter values
- Database error logs showing unexpected queries
Network Indicators:
- HTTP requests to /include/make.php containing SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_server" AND uri="/include/make.php" AND (art="*'*" OR art="*SELECT*" OR art="*UNION*" OR art="*OR*" OR art="*AND*")
