# Impact :
***********
WordPress 3.4.2/4.7.13 Satoshi Themes 2.0 is prone to a vulnerability that lets attackers
upload arbitrary files because it fails to adequately sanitize user-supplied input.
An attacker can exploit this vulnerability to upload arbitrary code and execute
it in the context of the webserver process. This may facilitate unauthorized access
or privilege escalation; other attacks are also possible. This WordPress Theme is
vulnerable to CSRF file upload via ajaxupload.3.5.js. CSRF occurs when the web application
does not, or can not, sufficiently verify whether a well-formed, valid, consistent request
was intentionally provided by the user who submitted the request.
