DESCRIPTION:
Two vulnerabilities have been reported in Guruscript Freelancer
Marketplace Script, which can be exploited by malicious users to
conduct script insertion attacks.

Input passed via the "en_project_title" and "en_project_description"
POST parameters to post_project.php is not properly sanitised before
being stored and returned to the user. 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.

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