The vulnerability allows a remote attacker to bypass authorization.

The vulnerability exists due to unspecified error within the SSL VPN web portal when processing HTTP requests. A remote non-authenticated attacker can send a specially crafted HTTP request to the SSL VPN web portal and change password for arbitrary account.

Successful exploitation of the vulnerability may allow an attacker to login to the SSL VPN web portal with a new password and gain unauthorized access to network resources.

As a workaround, the vendor recommends disabling the SSL-VPN web portal service: 

	 config vpn ssl settings

	 unset source-interface

	 end
