Subject: Security alert: Remote user can access any file


Roxen Webserver 2.0 up to version 2.0.92 and 2.1 up to version 2.1.264
has a vulnerability that allows any user to retrieve any file from the
host with the privileges of the web server. Having the CGI-module
enabled escalates the problem by making it possible to run any
executable.

Systems affected

  All Roxen 2.0 releases on all OS's before 2.0.92.
  All Roxen 2.1 releases on all OS's before 2.1.264.
  
  Roxen Platform/SiteBuilder is not affected unless any
  of the following modules have been added to the server:

    * Normal File system
    * Restricted file system
    * User file system
    * Frontpage Script support
    * CGI scripting support
    * Fast CGI support
    * Plain filesystem

  These modules are NOT part of a normal Platform/SiteBuilder setup.

  Roxen versions 1.3 and earlier are not affected unless the
  unofficial de-UTF8 or URL rectifier modules are installed and
  enabled.

Solution

  An update package labeled 'Fix for file access vulnerability' is
  available from the Roxen 2.1 update server for users of the 2.1.247
  and 2.1.262 releases. Use the administration interface to download and
  install this fix. Note that the server needs to be restarted when the
  fix is installed.

  Patches and instructions how to apply them for all 2.x releases are
  available at
  http://download.roxen.com/
  on the download page for the version of Roxen you are using.

  All 2.x releases available on download.roxen.com are patched.

  Users of Roxen 1.3 should make sure that they do not have de-UTF8 or
  URL rectifier modules enabled in any virtual server.

Further information

  If you have questions post them on the Roxen mailing list or to
  bugs () roxen com. If you have a support contract with Roxen you can
  contact Roxen through the normal support channels.
