The ../ sequence is a system command used to "step up" one level in the file directory. By chaining several of these together—as seen in your prompt—an attacker attempts to leave the restricted application folder and reach the of the operating system. Why "Root"?
Thus, the full decoded path becomes: ../../../../root/
Successfully executing a file inclusion or path traversal attack can have severe consequences for an organization.

To prevent this attack vector, developers and system administrators should implement the following controls:
Whether you are reviewing or analyzing web server logs Thus, the full decoded path becomes:

Are you and reviewing the log outputs?
Then appending root/ leads to /root/ , which on Unix-like systems contains sensitive data such as the root user’s home directory, SSH keys, bash history, and other privileged files. To prevent this attack vector, developers and system
// VULNERABLE CODE EXAMPLE $page = $_GET['file']; include("/var/www/html/pages/" . $page); Use code with caution.
Successful exploitation of this flaw can lead to severe security breaches:
: Use an allow-list of permitted file names rather than trying to filter "bad" characters.
Using built-in file system functions that don't allow "stepping out" of a folder.
