Description¶
FatPipe MPVPN, WARP, and IPVPN appliances running the end-of-life firmware version 10.1.2r60p100 contain an OS command injection vulnerability in the xtremed daemon. An unauthenticated remote attacker with access to the affected management interface can submit crafted input to the AuthFormServlet endpoint, causing authentication data to be processed by a shell and allowing arbitrary commands to execute as root.
The affected management interface is disabled by default and must be affirmatively enabled by the customer before the endpoint becomes reachable. FatPipe recommends restricting management access to trusted administrative networks and using WAN access control lists to limit access to trusted sources.
Customers running the affected end-of-life firmware can contact FatPipe Support for help confirming their firmware version and upgrading to a current supported release at https://www.fatpipeinc.com/support/support, support@fatpipeinc.com, or +1 800-724-8521 (option 3).
