DESCRIPTION:
James Bercegay has reported a vulnerability in Dokeos, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "extAuthSource['newUser']" parameter in
claroline/inc/claro_init_local.inc.php is not properly verified
before being used to include files. This can be exploited to include
arbitrary files from local or external resources.

Successful exploitation requires that "register_globals" is enabled.

SOLUTION:
Edit the source code to ensure that input is properly verified or
disable "register_globals".
