What is the purpose of a path traversal attack?

Which is a common file used for directory traversal?
UNIX etc/passwd is a common file used to demonstrate directory traversal, as it is often used by crackers to try cracking the passwords. The following URLs may be vulnerable to this attack: An attacker can execute this attack like this:
Why are there so many directory traversal vulnerabilities?
Directory traversal has been the cause of numerous Microsoft vulnerabilities. Some web applications attempt to prevent directory traversal by scanning the path of a request URI for patterns such as ../.
What causes include to traverse to the root directory?
The repeated ../ characters after /home/users/phpguru/templates/ has caused include () to traverse to the root directory, and then include the UNIX password file /etc/passwd. UNIX etc/passwd is a common file used to demonstrate directory traversal, as it is often used by crackers to try cracking the passwords.
