(DokuWiki: Arbitrary command execution)

    'rgod' discovered that DokuWiki doesn't sanitize the X-FORWARDED-FOR
    HTTP header, allowing the injection of arbitrary contents - such as PHP
    commands - into a file. Additionally, the accessory scripts installed
    in the 'bin' DokuWiki directory are vulnerable to directory traversal
    attacks, allowing to copy and execute the previously injected code.
  
Impact :

    A remote attacker may execute arbitrary PHP (and thus probably system)
    commands with the permissions of the user running the process serving
    DokuWiki pages.
  
Workaround :

    Disable remote access to the 'bin' subdirectory of the DokuWiki
    installation. Remove the directory if you don't use the scripts in
    there."
