TITLE:
Blogn Cross-Site Scripting and Cross-Site Request Forgery

SECUNIA ADVISORY ID:
SA31662

VERIFY ADVISORY:
http://secunia.com/advisories/31662/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Blogn 1.x
http://secunia.com/product/12775/

DESCRIPTION:
Two vulnerabilities have been reported in Blogn, which can be
exploited by malicious people to conduct cross-site scripting and
cross-site request forgery attacks.

1) Input passed to unspecified parameters is not properly sanitised
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

2) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
request. This can be exploited to edit content without valid user
credentials, by enticing a logged-in user to visit a malicious site.

The vulnerabilities are reported in version 1.9.7 and all previous
versions.

SOLUTION:
Update to version 1.9.8.
