FluxBB 1.5.3 Multiple Remote Vulnerabilities
|
|
|
|
|
|
Vendor: FluxBB
|
|
Product web page: http://www.fluxbb.org
|
|
Affected version: 1.5.3
|
|
|
|
Summary: FluxBB is fast, light, user-friendly forum software for your website.
|
|
|
|
Desc: FluxBB suffers from a cross-site scripting, cross-site request forgery
|
|
and URL redirect vulnerability. 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 perform certain actions with administrative
|
|
privileges if a logged-in user visits a malicious web site. Input passed via the
|
|
'redirect_url' parameter in 'misc.php' script is not properly verified before
|
|
being used to redirect users. This can be exploited to redirect a user to an
|
|
arbitrary website e.g. when a user clicks a specially crafted link to the
|
|
affected script hosted on a trusted domain. It also fails to properly sanitize
|
|
user-supplied input to the 'form[board_title]' POST parameter in the 'admin_options.php'
|
|
script. Attackers can exploit this weakness to execute arbitrary HTML and script
|
|
code in a user's browser session.
|
|
|
|
Tested on: Microsoft Windows 7 Ultimate SP1 (EN)
|
|
Apache 2.4.2 (Win32)
|
|
PHP 5.4.7
|
|
MySQL 5.5.25a
