that specifically block "etc/passwd" or "boot.ini" patterns in URI parameters. Why This Specific Pattern is Dangerous
: In the context of web applications, paths like this might be used to test if a web application or its server is vulnerable to directory traversal attacks. Such attacks allow an attacker to access files outside the intended directory, potentially leading to information disclosure.
This is a classic attack targeting Unix/Linux systems, trying to read the sensitive /etc/passwd file by escaping out of the web root using ../ sequences (here obfuscated with ....// which resolves to ../ after normalization in some systems).
