CVE-2026-7115

Vulnerability

Analysis

The vulnerability resides in the delete.php file of code-projects Employee Management System 1.0. The id parameter from the GET request is directly concatenated into a DELETE SQL statement without any sanitization or parameterization: $result = mysqli_query($conn, "DELETE FROM employee WHERE id=$id") [1]. This allows an attacker to inject arbitrary SQL commands through the id parameter.

Exploitation

An attacker can exploit this by sending a crafted GET request to /delete.php?id=<payload>. The provided proof-of-concept uses a time-based blind technique with a sleep(10) payload to confirm database-side execution [1]. The attack is remotely exploitable without authentication, as the endpoint is publicly accessible. The exploit has been publicly disclosed, increasing the risk of active exploitation.

Impact

Successful exploitation could allow an attacker to manipulate or delete arbitrary records from the database, depending on database permissions. Using blind SQL injection techniques, an attacker can infer database structure and contents. Additionally, time-delay payloads can degrade application availability by forcing expensive database operations [1].

Mitigation

As of the publication date, no official patch has been released. The vendor (code-projects) has not issued an update. The recommended mitigation is to use parameterized queries (prepared statements) to prevent SQL injection. Until a fix is applied, administrators should restrict access to the delete.php endpoint or implement a web application firewall (WAF) to block malicious payloads.
