CVE-2025-6471
📋 TL;DR
A critical SQL injection vulnerability exists in code-projects Online Bidding System 1.0's administrator interface. Attackers can remotely exploit the 'aduser' parameter to execute arbitrary SQL commands, potentially compromising the database. All deployments of version 1.0 are affected.
💻 Affected Systems
- code-projects Online Bidding System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, remote code execution, and full system takeover.
Likely Case
Database information disclosure, session hijacking, and privilege escalation to administrator level.
If Mitigated
Limited impact with proper input validation and WAF protection, potentially only error messages exposed.
🎯 Exploit Status
Exploit requires access to administrator interface but no authentication bypass needed for SQL injection itself
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider implementing parameterized queries and input validation manually.
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the /administrator endpoint
Input Validation Filter
allAdd server-side validation to sanitize 'aduser' parameter before processing
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test the /administrator endpoint with SQL injection payloads in the aduser parameterCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return appropriate error handling📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Unusual database queries from web server IP
- Multiple failed login attempts to /administrator
Network Indicators:
- SQL keywords in HTTP POST parameters to /administrator
- Unusual database port traffic from web server
SIEM Query:
source="web_logs" AND uri="/administrator" AND (param="aduser" AND value MATCHES "(?i)(union|select|insert|delete|update|drop|exec|--|#)")
