Recommended actions to resolve this vulnerability, in priority order.
- Remove
Remove
CodeAstro Leave Management System /admin/add_staff.phpfrom your environment.If the add_staff.php functionality is not required, temporarily disable or remove /admin/add_staff.php from the server to prevent remote exploitation until a secure fix is deployed.
- Configuration
Modify /admin/add_staff.php to eliminate SQL injection by using parameterized queries (prepared statements) for all database operations involving email_id and by validating/sanitizing the email_id input (e.g., enforce an email regex/whitelist and reject unexpected characters) before use in any query.
CodeAstro Leave Management System /admin/add_staff.php input handling for email_id = parameterized queries + input validation/sanitization - Compensating control
Until the code is fixed, restrict access to the /admin/ area (including /admin/add_staff.php) to trusted IP addresses or place the admin interface behind a VPN, and/or deploy WAF rules to block SQL injection payloads targeting email_id parameters.
- Operational
Search application and server logs for suspicious requests or signs of exploitation against /admin/add_staff.php (requests manipulating email_id); if compromise is suspected, investigate further, restore affected systems from known-good backups, and rotate any potentially exposed credentials.
