Vulnerable Systems:
* Moxiecode Systems AB Plupload 1.5.4
* WordPress 3.4.2 and prior
Plupload contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate certain unspecified input before returning it to the user. This may allow an attacker to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
