A vulnerable PHP endpoint might contain:

The string ....-2F-2F....-2F-2F....-2F-2Fetc-2Fpasswd is a malicious payload used in Path Traversal attacks to bypass security filters and read restricted system files. It utilizes nested traversal techniques and URL encoding ( ) to access sensitive information like /etc/passwd .

In a vulnerable web application, an attacker might use sequences like (often URL-encoded as By repeating this several times, an attacker moves

: Each ../ tells the operating system to move "up" one directory level. By repeating this several times, an attacker moves from a public folder (like /var/www/html/ ) all the way up to the Root Directory ( / ), then navigates back down into /etc/ to read the passwd file. 2. Why /etc/passwd ?

Even without passwords, it is a file for path traversal vulnerabilities.
