DESCRIPTION:
Two vulnerabilities have been discovered in the uCan Post plugin for
WordPress, which can be exploited by malicious users and malicious
people to conduct script insertion attacks.

1) Input passed via the "ucan_submission_title" parameter to
index.php when creating a post is not properly sanitised before being
used. This can be exploited to insert arbitrary HTML and script code,
which will be executed in a user's browser session in context of an
affected site when the malicious data is being viewed.

2) Input passed via the "ucan_submission_guest_name" parameter to
index.php when creating a post is not properly sanitised before being
used. This can be exploited to insert arbitrary HTML and script code,
which will be executed in a user's browser session in context of an
affected site when the malicious data is being viewed.

Successful exploitation of this vulnerability requires that "User
Level required to create posts" is set to "Guest" and that the
attacker is not logged in.

The vulnerabilities are confirmed in version 1.0.09. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
