Executive Summary

CVE-2026-37593 is a critical SQL injection vulnerability found in the Online Employees Work From Home Attendance System v1.0 developed by Sourcecodester.

The flaw exists in the file /wfh_attendance/admin/view_att.php, specifically in the handling of the 'id' parameter in the URL query string.

Because the 'id' parameter is not properly sanitized or validated, an attacker can inject arbitrary SQL code into the database query.

This allows the attacker to execute unauthorized SQL commands, such as retrieving database information or manipulating data.

Impact Analysis

This SQL injection vulnerability can have serious impacts including unauthorized disclosure of sensitive data stored in the attendance system's database.

Attackers can manipulate or extract data by injecting malicious SQL commands, potentially compromising employee attendance records or other confidential information.

Such unauthorized access can lead to data breaches, loss of data integrity, and disruption of the attendance system's normal operations.

Detection Guidance

This vulnerability can be detected by testing the `id` parameter in the URL `/wfh_attendance/admin/view_att.php` for SQL injection. An example command to test this is to send a crafted HTTP GET request with a payload that attempts a UNION-based SQL injection.

• Use a curl command to test the injection point, for example: curl "http://<target>/wfh_attendance/admin/view_att.php?id=1' union select 1,2,3,4,5,6,7,8,sqlite_version(),10,11,12--+"
• Observe the response for database version information or SQL errors indicating successful injection.

The vulnerability arises from improper sanitization of the `id` parameter, so any input that manipulates the SQL query structure can be used to detect it.

Mitigation Strategies

To mitigate the SQL injection vulnerability in the Online Employees Work From Home Attendance System v1.0, immediate steps include:

• Avoid using the vulnerable endpoint `/wfh_attendance/admin/view_att.php` with untrusted input until a fix is applied.
• Implement proper input validation and sanitization on the `id` parameter to prevent injection of arbitrary SQL code.
• Use parameterized queries or prepared statements instead of directly concatenating user input into SQL queries.
• Restrict access to the vulnerable admin page to trusted users only, possibly by enforcing stricter authentication and authorization.
• Monitor logs for suspicious activity targeting the `id` parameter in the URL.
