SQL Injection in Employee Management System

A critical SQL injection vulnerability has been identified in the code-projects Employee Management System version 1.0. The vulnerability exists within the Admin Login Endpoint, specifically located in the /process/aprocess.php file. An unauthenticated attacker can exploit this flaw by sending a crafted HTTP request that manipulates the 'mailuid' argument. This manipulation allows for the injection and execution of arbitrary SQL commands against the underlying database. Remote exploitation of this vulnerability is possible and functional exploit code has been publicly disclosed. Organizations utilizing this software should restrict access to administrative endpoints and validate all user-supplied input to prevent database compromise.

Attack Chain

1. Attacker performs reconnaissance to identify the target web application running Employee Management System 1.0.
2. Attacker locates the login interface which routes requests to the /process/aprocess.php endpoint.
3. Attacker crafts a malicious HTTP POST request targeting the 'mailuid' parameter.
4. The input is passed directly into the SQL query without proper neutralization or sanitization.
5. The backend database executes the injected SQL commands.
6. The attacker leverages the resulting database access to extract information or bypass authentication mechanisms.

Impact

Successful exploitation of this SQL injection vulnerability can lead to unauthorized access to sensitive employee data stored in the database. Attackers may also be able to modify or delete data, or potentially escalate privileges within the application environment. Given the potential for unauthenticated access, the integrity and confidentiality of the employee management system are at significant risk.

Recommendation

Prioritize the following actions to mitigate risk associated with CVE-2026-76764:

• Deploy the provided Sigma rule to web server logs to detect exploitation attempts targeting the identified endpoint.
• Apply input validation and parameterized queries to the '/process/aprocess.php' script to neutralize the SQL injection vulnerability.
• Implement network-level access controls to restrict public access to the Admin Login Endpoint.
• Monitor logs for HTTP POST requests to '/process/aprocess.php' that contain SQL control characters or keywords in the 'mailuid' field.
