Executive brief
Payara Server, a Java-based application server used to run enterprise web applications, does not limit failed login attempts by default. This allows attackers to perform brute force attacks to guess administrator or user credentials, potentially gaining unauthorized access to the system and its hosted applications. While Payara includes optional attack protection features, they must be manually configured to be effective.
Technical details
The vulnerability stems from the lack of default rate-limiting or account lockout mechanisms for failed authentication attempts. An attacker can make repeated login requests to the Payara Server admin console or application authentication endpoints without triggering automatic account lockout or connection throttling. This is a network-reachable attack requiring only knowledge of valid usernames. The impact is credential compromise through brute force, leading to potential system takeover. Payara provides built-in attack protection features via the security configuration framework, but these require explicit administrator setup and are not enabled by default.
