📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, privilege escalation to admin, and potential remote code execution via database functions.
Likely Case
Unauthorized data access and modification, including exposure of tenant information, payment records, and administrative credentials.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
Exploitation requires authentication to access the admin panel where delete_category() function is called. SQL injection payloads are well-documented and easy to craft.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Replace vulnerable delete_category() function with parameterized queries. 2. Implement proper input validation and sanitization. 3. Update to a patched version if available from vendor.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to reject malicious SQL characters in category deletion requests
Add PHP validation: if(preg_match('/[\'"\;\-\-]/', $input)) { die('Invalid input'); }
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
ModSecurity rule: SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Isolate the vulnerable system behind a firewall with strict access controls
- Implement database monitoring and alerting for suspicious SQL queries
🔍 How to Verify
Check if Vulnerable:
Test the delete_category function with SQL injection payloads like ' OR '1'='1 in category parameterCheck Version:
Check the software version in admin panel or review rental/admin_class.php file headerVerify Fix Applied:
Verify that parameterized queries are implemented and test with same SQL injection payloads that should be rejected📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by admin panel access
- DELETE or SELECT queries with concatenated strings
Network Indicators:
- HTTP POST requests to admin endpoints with SQL keywords in parameters
- Unusual database connection patterns
SIEM Query:
source="web_logs" AND (uri="*admin*" AND (param="*' OR*" OR param="*;--*" OR param="*UNION*"))
