B usting the Hardcoded Password HOAX
The hardcoded password hoax is a myth that tells people that changing the hardcoded password on their system will only cause it to be compromised by malicious users. The truth is, this is far from the truth.
Input validation issue
Input validation is a security measure used to prevent malicious input from being passed to an application. This is typically accomplished through the use of regular expressions and includes escaping characters that are special to the operating system in order to limit their functionality. However, this can be bypassed by using JavaScript.
Preventing the input validation issue: Input validation should be caught by the software before it reaches any sensitive data on the device. Methods for input validation include using regular expressions and escaping characters with the help of JavaScript.
Solution for input validation issue: Input validation should occur before any sensitive data is stored on a device.
