CVE-2021-44610
📋 TL;DR
CVE-2021-44610 allows attackers to execute arbitrary SQL commands via multiple parameters in bloofoxCMS admin interface. This affects all bloofoxCMS installations running versions 0.5.1 through 0.5.2.1 with default configurations.
💻 Affected Systems
- bloofoxCMS
📦 What is this software?
Bloofoxcms by Bloofox
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, remote code execution via database functions, and full system takeover.
Likely Case
Database information disclosure, authentication bypass, and potential privilege escalation to admin access.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error-based information disclosure.
🎯 Exploit Status
SQL injection via GET parameters requires no authentication. Simple payloads can be crafted based on parameter names.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: None - bloofoxCMS appears abandoned
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch exists. Consider migrating to alternative CMS or implementing custom fixes with input validation.
🔧 Temporary Workarounds
Input Validation Filter
allAdd parameter validation in admin/index.php to sanitize all vulnerable parameters
Edit admin/index.php to add: $param = filter_var($_GET['param'], FILTER_SANITIZE_STRING); for each vulnerable parameter
Web Application Firewall Rules
allBlock SQL injection patterns targeting the vulnerable parameters
Add WAF rules to block requests containing SQL keywords in URLs, lang_id, tmpl_id, mod_rewrite, eta_doctype, meta_charset, default_group, page_group parameters
🧯 If You Can't Patch
- Restrict access to admin/index.php via IP whitelisting or authentication
- Implement database user with minimal permissions (SELECT only where possible)
🔍 How to Verify
Check if Vulnerable:
Test admin/index.php with SQL injection payloads in vulnerable parameters (e.g., admin/index.php?lang_id=1' OR '1'='1)Check Version:
Check bloofoxCMS version in configuration files or admin panelVerify Fix Applied:
Test same payloads after implementing fixes - should return error or sanitized output without SQL execution📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual parameter values in admin/index.php requests
- Multiple failed login attempts followed by parameter manipulation
Network Indicators:
- HTTP requests to admin/index.php with SQL keywords in parameters
- Unusual database query patterns from web server
SIEM Query:
web.url:*/admin/index.php* AND (web.query:*OR* OR web.query:*UNION* OR web.query:*SELECT* OR web.query:*INSERT*)
