Claroline mambo.inc.php includePath Parameter Remote File Inclusion
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

Claroline contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to claroline/auth/extauth/drivers/mambo.inc.php not properly sanitizing user input supplied to the 'includePath' variable. This may allow an attacker to include a file from a remote host that contains arbitrary commands which will be executed by the vulnerable script.
