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:
Update to Dokeos 1.8.
Edit the source code to ensure that input is properly verified or disable "register_globals".
