阻止恶意URL请求错误查询BBQ脚本代码

阻止恶意URL请求错误查询BBQ是一个简单的脚本，可保护您的网站免遭恶意URL请求。检查所有传入流量，并悄阻止掉一些恶意请教代码eval(，base64_和过长请求字符串。这是一个简单而可靠的解决方案，非常适合无法使用.htaccess的网站。该阻止脚本可作为WordPress的插件或独立的脚本用于任何PHP -Powered网站。

检查以下三部分URL请求:



1,Wordpress程序复制以下代码放入functions.php

function bbq_core() {
	
	$request_uri_array  = apply_filters('request_uri_items',  array('@eval', 'eval\(', 'UNION(.*)SELECT', '\(null\)', 'base64_', '\/localhost', '\%2Flocalhost', '\/pingserver', 'wp-config\.php', '\/config\.', '\/wwwroot', '\/makefile', 'crossdomain\.', 'proc\/self\/environ', 'usr\/bin\/perl', 'var\/lib\/php', 'etc\/passwd', '\/https\:', '\/http\:', '\/ftp\:', '\/file\:', '\/php\:', '\/cgi\/', '\.cgi', '\.cmd', '\.bat', '\.exe', '\.sql', '\.ini', '\.dll', '\.htacc', '\.htpas', '\.pass', '\.asp', '\.jsp', '\.tar', '\.bash', '\/\.git', '\/\.svn', ' ', '\<', '\>', '\/\=', '\.\.\.', '\+\+\+', '@@', '\/&&', '\/Nt\.', '\;Nt\.', '\=Nt\.', '\,Nt\.', '\.exec\(', '\)\.html\(', '\{x\.html\(', '\(function\(', '\.php\([0-9]+\)', '(benchmark|sleep)(\s|%20)*\('));
	$query_string_array = apply_filters('query_string_items', array('@@', '\(0x', '0x3c62723e', '\;\!--\=', '\(\)\}', '\:\;\}\;', '\.\.\/', '127\.0\.0\.1', 'UNION(.*)SELECT', '@eval', 'eval\(', 'base64_', 'localhost', 'loopback', '\%0A', '\%0D', '\%00', '\%2e\%2e', 'allow_url_include', 'auto_prepend_file', 'disable_functions', 'input_file', 'execute', 'file_get_contents', 'mosconfig', 'open_basedir', '(benchmark|sleep)(\s|%20)*\(', 'phpinfo\(', 'shell_exec\(', '\/wwwroot', '\/makefile', 'path\=\.', 'mod\=\.', 'wp-config\.php', '\/config\.', '\$_session', '\$_request', '\$_env', '\$_server', '\$_post', '\$_get'));
	$user_agent_array   = apply_filters('user_agent_items',   array('acapbot', '\/bin\/bash', 'binlar', 'casper', 'cmswor', 'diavol', 'dotbot', 'finder', 'flicky', 'md5sum', 'morfeus', 'nutch', 'planet', 'purebot', 'pycurl', 'semalt', 'shellshock', 'skygrid', 'snoopy', 'sucker', 'turnit', 'vikspi', 'zmeu'));
	
	$request_uri_string  = false;
	$query_string_string = false;
	$user_agent_string   = false;
	
	if (isset($_SERVER['REQUEST_URI'])     && !empty($_SERVER['REQUEST_URI']))     $request_uri_string  = $_SERVER['REQUEST_URI'];
	if (isset($_SERVER['QUERY_STRING'])    && !empty($_SERVER['QUERY_STRING']))    $query_string_string = $_SERVER['QUERY_STRING'];
	if (isset($_SERVER['HTTP_USER_AGENT']) && !empty($_SERVER['HTTP_USER_AGENT'])) $user_agent_string   = $_SERVER['HTTP_USER_AGENT'];
	
	if ($request_uri_string || $query_string_string || $user_agent_string) {
		
		if (
			
			// strlen( $_SERVER['REQUEST_URI'] ) > 255 || // optional
			
			preg_match('/'. implode('|', $request_uri_array)  .'/i', $request_uri_string)  || 
			preg_match('/'. implode('|', $query_string_array) .'/i', $query_string_string) || 
			preg_match('/'. implode('|', $user_agent_array)   .'/i', $user_agent_string) 
			
		) {
			
			bbq_response();
			
		}
		
	}
	
}
add_action('plugins_loaded', 'bbq_core');

function bbq_response() {
	
	header('HTTP/1.1 403 Forbidden');
	header('Status: 403 Forbidden');
	header('Connection: Close');
	
	exit;
	
}

2，PHP脚本独立版，置于其他类PHP程序下

<?php

$request_uri = $_SERVER['REQUEST_URI'];
$query_string = $_SERVER['QUERY_STRING'];
$user_agent = $_SERVER['HTTP_USER_AGENT'];
