🔧 Temporary Workarounds

Web Application Firewall (WAF)

all

Deploy a WAF with SQL injection protection rules to block malicious requests.

Input Validation Filter

all

Implement application-level input validation to reject suspicious SQL characters.

🧯 If You Can't Patch

  • Isolate the Turasistan system from the internet and restrict network access
  • Implement strict database user permissions and monitor for unusual SQL queries

🔍 How to Verify

Check if Vulnerable:

Check Turasistan version in admin panel or configuration files. If version is earlier than 20230911, system is vulnerable.

Check Version:

Check Turasistan admin interface or configuration files for version information.

Verify Fix Applied:

Verify version is 20230911 or later in admin panel and test SQL injection attempts are blocked.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in application logs
  • Multiple failed login attempts with SQL syntax
  • Long or malformed URL parameters in access logs

Network Indicators:

  • HTTP requests containing SQL keywords (SELECT, UNION, DROP, etc.)
  • Abnormal database query patterns from application server

SIEM Query:

source="turasistan_logs" AND ("SQL syntax" OR "mysql_error" OR "sqlite_error") OR http.uri contains "UNION" OR "SELECT"
