CVE-2026-110003: Azul Payara Administration REST Interface Authentication Bypass via X-GlassFish-authToken Header Leading to Remote Code Execution
A vulnerability in the administration REST interface of Azul Payara allows a remote, unauthenticated attacker to bypass secure-admin remote-access restrictions by supplying an arbitrary value in the X-GlassFish-authToken HTTP header. The header's presence waives the remote-rejection check before the token is validated, and an invalid token falls through to password-based authentication, which succeeds without credentials on default domains configured with an empty administrative password. Successful exploitation grants execution of arbitrary administrative commands, equivalent to complete compromise of the server.
Event History
Frequently Asked Questions
Which deployments are exposed to unauthenticated remote compromise?
Deployments with the administration REST interface reachable remotely are exposed when secure-admin remote-access restrictions can be bypassed and the default domain has an empty administrative password. An attacker does not need valid credentials in that configuration.
What does an attacker need to send to exploit this issue?
The attacker must make a request to the administration REST interface containing the X-GlassFish-authToken HTTP header with an arbitrary value. The header bypasses the remote-rejection check, and an invalid token can fall through to password-based authentication without credentials where the administrative password is empty.
What is the impact after successful exploitation?
A successful attacker can execute arbitrary administrative commands on the server. This is equivalent to complete compromise of the affected server.
How can I determine whether my environment is at risk?
Verify whether the administration REST interface is remotely reachable and whether the default domain uses an empty administrative password. Also determine whether requests carrying an arbitrary X-GlassFish-authToken header can reach that interface.
