- Limit authenticated access to the application to trusted users and review existing accounts.
- Ensure that all request parameters, including timezone values, are validated and that database access uses parameterized queries rather than raw query interpolation.
- Apply least privilege to the database account used by the application to reduce the impact of injected queries.
Detection guidance
- Review application logs for timezone parameter values containing unexpected special characters or SQL keywords.
- Monitor database logs for query errors or unusual query patterns originating from the application account.
- Treat anomalous authenticated sessions that send malformed input as a priority for investigation.
