Technical Details & Description:
================================
A non-persistent cross site scripting vulnerability has been discovered
in the official Wordpress Theme Dosimple v2.0 web-application.
The vulnerability allows remote attackers to inject own malicious script
codes with non-persistent attack vector to compromise browser to
web-application requests from the client-side.

The cross site scripting vulnerabilities are located in the `s`
parameter. The request method to inject the malicious script code is GET
and
the attack vector of the vulnerability is non-persistent on client-side.

Successful exploitation of the vulnerability results in session
hijacking, non-persistent phishing attacks, non-persistent external
redirects to malicious source and non-persistent manipulation of
affected application modules.

Request Method(s):
[+] GET

Vulnerable Parameter(s):
[+] s
