🔧 Temporary Workarounds

WAF Rule Implementation

all

Block SQL injection patterns targeting /index.php/stock/item_select endpoint

# Example ModSecurity rule:
SecRule REQUEST_URI "@streq /index.php/stock/item_select" \
"id:1001,phase:2,deny,status:403,msg:'Blocking SQLi attempt'" \
"chain"
SecRule ARGS:q "@detectSQLi"

Input Validation Filter

all

Add parameter validation before database query execution

# PHP example:
$q = filter_var($_GET['q'], FILTER_SANITIZE_STRING);
$q = mysqli_real_escape_string($connection, $q);

🧯 If You Can't Patch

  • Block external access to /index.php/stock/item_select via firewall rules
  • Implement strict input validation and parameterized queries in the vulnerable file

🔍 How to Verify

Check if Vulnerable:

Send GET request to /index.php/stock/item_select?q=1' AND '1'='1 and check for SQL error responses or unexpected behavior

Check Version:

Check system version in admin panel or review source code comments for version 1.0 references

Verify Fix Applied:

Test with SQL injection payloads after applying fixes; verify no database errors or unauthorized data access occurs

📡 Detection & Monitoring

Log Indicators:

  • SQL syntax errors in web server logs
  • Unusual database queries from web application
  • Multiple requests to /index.php/stock/item_select with special characters

Network Indicators:

  • HTTP requests containing SQL keywords (SELECT, UNION, etc.) in q parameter
  • Unusual traffic patterns to vulnerable endpoint

SIEM Query:

source="web_logs" AND uri="/index.php/stock/item_select" AND (query="*'*" OR query="*SELECT*" OR query="*UNION*")
