Vulnerability Exploitability eXchange (VEX) is a platform that allows organizations to track and manage vulnerabilities in their systems and devices. VEX is designed to provide a centralized repository for vulnerability information, making it easier for organizations to identify and prioritize vulnerabilities that need to be addressed. VEX was created by Carnegie Mellon University's CERT Coordination Center (CERT/CC) as a way to improve the management of vulnerabilities and reduce the risk of exploitation. It is based on the Common Vulnerability Scoring System (CVSS), which is a widely-adopted standard for evaluating the severity of vulnerabilities. VEX provides a number of benefits for organizations that use it. By centralizing vulnerability information, it makes it easier for organizations to identify and prioritize vulnerabilities that need to be addressed. It also provides a way for organizations to track the progress of vulnerabilities as they are being addressed, ensuring tha
SQL injection is a type of cyber attack that allows attackers to insert malicious code into a web application's SQL statements. This can enable attackers to gain unauthorized access to sensitive data, to manipulate or delete data, or to execute arbitrary commands on the underlying database. SQL injection attacks are possible because many web applications do not properly validate user-supplied input before using it in SQL statements. This allows attackers to craft input that contains malicious SQL code, which is then executed by the database. To illustrate how SQL injection works, let's consider the following example in Java: String username = request.getParameter("username"); String password = request.getParameter("password"); String query = "SELECT * FROM users WHERE username='" + username + "' AND password='" + password + "'"; Statement stmt = connection.createStatement(); ResultSet rs = stmt.executeQuery(que
