### SUMMARY

CYSTEME Finder is an admin file manager plugin for wordpress that fails to check cookie data in the request 
to http://server/wp-content/plugins/cysteme-finder/php/connector.php 

This allows attackers to upload, download, and browse the remote file system.

Simply replacing wphome with any other directory path will return file information for that directory. 
If you want to download that file, get the hash value for the file and include it in the following request:
 
Will download /etc/passwd
http://server/wp-content/plugins/cysteme-finder/php/connector.php?wphome=/etc&cmd=file&target=l1_cGFzc3dk&download=1

### File Upload

As with downloading the files, you will need the hash value for the target directory. With the hash value, send a payload similar to the following.
