This rule is deprecated, and will eventually be removed.
Reading Standard Input is security-sensitive. It has led in the past to the following vulnerabilities:
It is common for attackers to craft inputs enabling them to exploit software vulnerabilities. Thus any data read from the standard input (stdin)
can be dangerous and should be validated.
This rule flags code that reads from the standard input.
Ask Yourself Whether
- data read from the standard input is not sanitized before being used.
You are at risk if you answered yes to this question.
Recommended Secure Coding Practices
Sanitize all data read from the standard input before using it.
Sensitive Code Example
using System;
public class C
{
public void Main()
{
Console.In; // Sensitive
var code = Console.Read(); // Sensitive
var keyInfo = Console.ReadKey(...); // Sensitive
var text = Console.ReadLine(); // Sensitive
Console.OpenStandardInput(...); // Sensitive
}
}
Exceptions
This rule does not raise issues when the return value of the Console.Read Console.ReadKey or
Console.ReadLine methods is ignored.
using System;
public class C
{
public void Main()
{
Console.ReadKey(...); // Return value is ignored
Console.ReadLine(); // Return value is ignored
}
}
