Null Byte Injection
Null byte injection is a type of attack that is caused by inserting a null byte or a string of zeros into a data input field. In computer systems, null bytes are used to indicate the end of a string, and in programming languages, they are often used as a delimiter for strings.
When a null byte is injected into a data input field, it can cause a system to misinterpret the data that follows it. This can lead to security vulnerabilities such as arbitrary code execution, allowing an attacker to gain unauthorized access to a system, steal data, or cause other types of damage.
This type of attack can be especially dangerous in web applications because it can be easily accomplished by an attacker manipulating the parameters of an HTTP request. As a result, it is important for application developers to be aware of this vulnerability and take steps to prevent null byte injection attacks from occurring.
