Medium Nessus Plugin ID 43127


The remote FreeBSD host is missing a security-related update.


secunia reports :

Russ McRee has discovered some vulnerabilities in Pligg, which can be exploited by malicious people to conduct cross-site scripting and request forgery attacks.

Input passed via the 'Referer' HTTP header to various scripts (e.g.
admin/admin_config.php, admin/admin_modules.php, delete.php, editlink.php, submit.php, submit_groups.php, user_add_remove_links.php, and user_settings.php) 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.

The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. create an arbitrary user with administrative privileges if a logged-in administrative user visits a malicious website.


Update the affected package.
