DESCRIPTION:
Aliaksandr Hartsuyeu has reported two vulnerabilities in Clever Copy,
which can be exploited by malicious people to conduct script insertion
attacks.
Input passed to the "Referer" and "X-Forwarded-For" HTTP headers
isn't properly sanitised before being used. This can be exploited to
inject arbitrary HTML and script code, which will be executed in an
administrator's browser session in context of an affected site when
the malicious user data is viewed via the statistics functionality.
The vulnerabilities have been reported in versions 3.0, 2.0, and
2.0a. Other versions may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
