Attack-Flow Graph

Executive Summary

This vulnerability is an authenticated Remote Code Execution (RCE) issue found in the GlassFish Administration Console. It allows a user who has access to the administration panel to send specially crafted requests that execute arbitrary operating system commands. These commands run with the same privileges as the application service user, potentially allowing significant control over the affected system.

Impact Analysis

The impact of this vulnerability is severe because it enables an authenticated user to execute arbitrary commands on the server hosting the GlassFish Administration Console. This can lead to full compromise of the system, including unauthorized data access, modification, or deletion, disruption of services, and potential further exploitation within the network.

Compliance Impact

This vulnerability allows an authenticated user to execute arbitrary operating system commands with the privileges of the application service user via the GlassFish Administration Console.

Such unauthorized command execution can lead to data breaches, unauthorized access, and potential manipulation or destruction of sensitive data.

Consequently, this vulnerability could negatively impact compliance with standards and regulations like GDPR and HIPAA, which require strict controls to protect sensitive personal and health information from unauthorized access and breaches.
