JBoss Management Console Information Disclosure

Description

The vulnerability exists in the JBoss Management Console’s Server Information endpoint, which is accessible without proper authentication. This endpoint, typically located at /web-console/ServerInfo.jsp, reveals detailed information about the application server environment such as the application server type, its configuration, runtime parameters, and potentially other embedded information. Attackers leveraging this vulnerability can easily detect key phrases like 'Application Server' and 'Management Console', which indicate that sensitive details about the server are being exposed. Although the severity of this weakness is classified as low, the leakage of such internal information provides adversaries with valuable insights that could be used to craft further targeted attacks, including those that might bypass authentication or elevate privileges. The exposure of server configuration details through this endpoint can represent a critical step in a multi-stage exploit where attackers gather intelligence to map out the network and determine other vulnerable points in the infrastructure. Best practices recommend that administrative endpoints like these be adequately secured or disabled in production environments to prevent unauthorized access, thereby minimizing the risk of an attacker using the disclosed data to compromise the system. In environments where this information disclosure remains unmitigated, subsequent attacks may include unauthorized administration, lateral movement, or configuration-based compromises, ultimately undermining the security posture of the overall system.

Impact

Exploitation allows attackers to retrieve sensitive configuration and runtime information about the JBoss Application Server. This information can be leveraged to plan further attacks such as unauthorized access, privilege escalation, or lateral movement, potentially leading to broader system compromise.
