To prevent buffer overflow attacks, programmers must ensure that they allocate sufficient memory to store the data and validate the user's input.Ĥ. An attacker sends more data than a buffer can handle, causing the application to crash or execute arbitrary code. Buffer overflows: Buffer overflow attacks exploit vulnerabilities in the memory management of an application. To mitigate XSS attacks, input validation and output encoding must be used.ģ. This type of attack is particularly dangerous because it can allow an attacker to steal sensitive information, such as login credentials. Cross-Site Scripting (XSS): XSS attacks occur when an attacker injects malicious scripts into a webpage, which then execute in the user's browser. To prevent injection attacks, you must use parameterized queries and avoid concatenating user input with SQL statements.Ģ. For example, SQL injection attacks exploit vulnerabilities in the application's code to access and modify sensitive data. Injection attacks: Injection attacks occur when an attacker sends malicious input to an application, which is then executed unintentionally by the application. There are several types of vulnerabilities that attackers can exploit in data validation and input handling. As a result, it is crucial to understand the different types of vulnerabilities that exist in data validation and input handling, and how to mitigate them. In other words, attackers may try to manipulate the data by exploiting vulnerabilities in the input validation process. This is because when applications accept input from users, they must validate and sanitize it to prevent malicious inputs that may cause the system to behave unexpectedly. When it comes to cybersecurity, one of the most common areas that attackers exploit is data validation and input handling.
