Blocked by buffer overflow protection8/18/2023 Overwriting memory: If the program does not correctly validate the input size, it will try to store the input in a buffer that is not large enough to hold it, causing the excess data to be written to the adjacent memory.Sending the malicious input: The attacker then sends the malicious input to the program, either by directly interacting with the program or by tricking a user into entering the input on their behalf.This input is usually designed to exceed the buffer’s capacity and overwrite other parts of the program’s memory. Crafting malicious input: The attacker must then create a carefully crafted input, often referred to as arbitrary code, designed to exploit the vulnerability in the program.Identifying a vulnerable program: The attacker must first identify a program vulnerable to buffer overflow attacks, typically by finding a program that does not properly validate the size or format of the input it receives. General Attack Flow: How It WorksĪ buffer overflow attack involves several stages: To prevent these types of vulnerabilities, developers must carefully validate input and ensure that their programs can handle unexpected data without crashing or becoming vulnerable to attack. These weaknesses all involve problems with how a program handles data in memory buffers, which can lead to buffer overflows and other security vulnerabilities.
