-page-....-2f-2f....-2f-2f....-2f-2fetc-2fpasswd

The string you've provided, -page-....-2F-2F....-2F-2F....-2F-2Fetc-2Fpasswd , is a classic example of a or Local File Inclusion (LFI) attack payload.

: This usually refers to a parameter in a URL (e.g., ://example.com... ). Attackers target these parameters because they often control which file the server loads. -page-....-2F-2F....-2F-2F....-2F-2Fetc-2Fpasswd

The given pattern resembles capturing an exploit attempt against a parameter named page . The string you've provided, -page-

: Attackers often look for sensitive files to access or to check if a system is vulnerable. The /etc/passwd file, being readable by all users, can provide valuable information about the system's users and their account statuses. Attackers target these parameters because they often control

The /etc/passwd file is readable by all users on the system, which allows for the retrieval of usernames and associated information. However, to enhance security, passwords are no longer stored in /etc/passwd . Instead, they are kept in /etc/shadow , which is only readable by root, ensuring that only authorized users can access the passwords.

The pattern might suggest a path traversal or a way to access sensitive files through a web interface. For example, a poorly secured web application might allow an attacker to access arbitrary files on the server by manipulating URL parameters.

: This is a double-encoded or "nested" traversal sequence. While ../ (encoded as %2E%2E%2F ) is standard, attackers use variations like ....// or ..%252f.. to bypass simple security filters that only look for a single ../ .
