Wildfly Default Login Scanner

Wildfly is a flexible, lightweight, managed application runtime used for building Java applications. It is widely adopted by developers and enterprises for deploying and managing Java EE applications due to its modular framework and ease of use. Large corporations and web hosting services utilize Wildfly to efficiently execute their Java-based applications, supporting cloud-native development practices. The software can be used for both local and distributed environments, with robust administrative capabilities making it suitable for various deployment scenarios. It offers extensive tools for application management and monitoring, suitable for businesses needing scalable application solutions. Wildfly is known for its rapid startup times and efficient resource consumption, making it a favorable choice for developers.

The Default Login vulnerability in Wildfly occurs when the default administrator credentials are left unchanged, allowing unauthorized access. Attackers can exploit this weakness to gain admin-level access, potentially compromising system security. This issue is critical as it opens the system to unauthorized control, data manipulation, or data theft. Default credentials are often added by vendors for account setup convenience, but if not changed, they become a significant security hole. Detecting such vulnerabilities is essential to mitigate unauthorized administration access. Understanding the risk associated with default logins helps in improving overall security posture.

The vulnerability detail involves the misuse of default credentials stored legitimately within the application. Attackers can perform a simple login using these defaults if they aren't changed post-deployment. The vulnerable endpoint specifically is the management interface of Wildfly, typically accessed via HTTP requests. In this case, requests targeting the "/management" path with default credentials grant full administrative privileges if conditions are met. The vulnerability is detected by checking specific indicators in response headers and bodies and matching against known version identifiers. The persistence of default credentials is inherently risky and demands immediate remedial action upon any detection.

When exploited by malicious actors, this vulnerability could lead to several adverse effects. These effects include unauthorized system control, data breaches, the introduction of malicious scripts or code, and potential denial of service. Compromised systems might be used as launch pads for broader attacks against networks or other services. Additionally, data integrity and confidentiality might be impacted, leading to significant business and revenue losses. The exploitation of such a vulnerability also undermines user trust and legal compliance, necessitating prompt corrective measures.
