Claroline extAuthSource Parameter Array Remote File Include Vulnerability

Vulnerability Assessment Summary
Tries to read a local file with Claroline

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP script that is affected by a
remote file inclusion attack.

Description :

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 'extAuthSource' parameter array before using it
to include PHP code in the 'claroline/inc/claro_init_local.inc.php'
script. 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.
