CVE-2026-90822: OS Command Injection
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).
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Leave the affected management interface disabled if it is not required. Do not affirmatively enable it; it is disabled by default and must be affirmatively enabled by the customer before the endpoint becomes reachable.
FatPipe management interface management interface enabled = disabled (ensure not affirmatively enabled) - Configuration
Restrict management access to trusted administrative networks and use WAN access control lists to permit connections only from authorized source addresses.
WAN access control lists (ACLs) permit source addresses = authorized source addresses only - Compensating control
Avoid exposing the management interface directly to the public Internet.
Event History
Frequently Asked Questions
Which deployments are exposed to remote exploitation?
Only FatPipe MPVPN, WARP, and IPVPN appliances running end-of-life firmware 10.1.2r60p100 are affected, and the management interface must have been affirmatively enabled. The interface is disabled by default, so appliances that have not enabled it do not expose the vulnerable endpoint.
Does an attacker need credentials or user interaction?
No. An unauthenticated remote attacker can exploit the issue if they can access the affected management interface and send crafted input to the AuthFormServlet endpoint.
What level of access could exploitation provide?
Successful exploitation allows arbitrary OS commands to execute as root on the appliance. This can result in full compromise of confidentiality, integrity, and availability.
What can be done if the affected firmware cannot be replaced immediately?
Disable the management interface if it is not required. If it must remain enabled, restrict management access to trusted administrative networks and use WAN access control lists to allow only trusted source addresses.
