Synopsis
========

Remote attackers can upload and execute arbitrary PHP scripts, another
flaw reveals the full path of scripts.

Background
==========

phpWebSite provides a complete web site content management system.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /   Vulnerable   /                Unaffected
    -------------------------------------------------------------------
  1  www-apps/phpwebsite      < 0.10.0-r2                 >= 0.10.0-r2

Description
===========

NST discovered that, when submitting an announcement, uploaded files
aren't correctly checked for malicious code. They also found out that
phpWebSite is vulnerable to a path disclosure.

Impact
======

A remote attacker can exploit this issue to upload files to a directory
within the web root. By calling the uploaded script the attacker could
then execute arbitrary PHP code with the rights of the web server. By
passing specially crafted requests to the search module, remote
attackers can also find out the full path of PHP scripts.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All phpWebSite users should upgrade to the latest available version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/phpwebsite-0.10.0-r2"
