- code-projects Staff Audit System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution through database functions.
Likely Case
Unauthorized data access, extraction of sensitive staff information, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only read access to non-sensitive data.
🎯 Exploit Status
Public exploit details available on GitHub. SQL injection via Search parameter requires minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the Search parameter before processing
Modify /search_index.php to validate and sanitize user input using prepared statements or parameterized queries
Web Application Firewall Rule
allBlock SQL injection patterns in the Search parameter
Add WAF rule: deny requests containing SQL keywords in Search parameter
🧯 If You Can't Patch
- Implement network segmentation to restrict access to vulnerable system
- Deploy web application firewall with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Test /search_index.php with SQL injection payloads in Search parameter (e.g., Search=test' OR '1'='1)Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts after search operations
- Long or malformed Search parameter values in web logs
Network Indicators:
- HTTP requests to /search_index.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/search_index.php" AND (Search CONTAINS "UNION" OR Search CONTAINS "SELECT" OR Search CONTAINS "OR '1'='1'")
