Eclipse: Security Vulnerabilities
An authenticated Remote Code Execution (RCE) vulnerability was identified in GlassFish's Administration Console. A user with access to the panel can send crafted requests that allow the execution of arbitrary operating system commands with the privileges of the application service user.

A critical Remote Code Execution (RCE) vulnerability was identified in the server-side template rendering mechanism used by the Glassfish gadget handler. The application processes .xml files and evaluates user-supplied values within a context where Expression Language (EL) “expressions” are processed without proper sanitization or escaping. By injecting expressions such as #{7*7}, the server returns 49, confirming server-side EL evaluation. This issue allows a remote attacker to fully compromise the underlying host, enabling capabilities as reading/modifying data, executing arbitrary commands, persistence, and lateral movement.

A TCP client can perform a TLS handshake and present the server name extension with a server name that is accepted by a server wildcard name, e.g. if the server is configured with a certificate accepting *.example.com, any XYZ.example.com where xyz is a valid name can be used.

In Eclipse Jetty, the HTTP/1.1 parser is vulnerable to request smuggling when chunk extensions are used, similar to the "funky chunks" techniques outlined here:
* https://w4ke.info/2025/06/18/funky-chunks.html
* https://w4ke.info/2025/10/29/funky-chunks-2.html
Jetty terminates chunk extension parsing at \r\n inside quoted strings instead of treating this as an error.
POST / HTTP/1.1
Host: localhost
Transfer-Encoding: chunked
1;ext="val
X
0
GET /smuggled HTTP/1.1
...
Note how the chunk extension does not close the double quotes, and it is able to inject a smuggled request.

In Eclipse Jetty, the class JASPIAuthenticator initiates the authentication checks, which set two ThreadLocal variable.
Upon returning from the initial checks, there are conditions that cause an early return from the JASPIAuthenticator code without clearing those ThreadLocals.
A subsequent request using the same thread inherits the ThreadLocal values, leading to a broken access control and privilege escalation.

An unsafe parsing of OpenMQ's configuration, allows a remote attacker to read arbitrary files from a MQ Broker's server. A full exploitation could read unauthorized files of the OpenMQ’s host OS. In some scenarios RCE could be achieved.

In Eclipse Jetty, versions 12.0.0-12.0.31 and 12.1.0-12.0.5, class GzipHandler exposes a vulnerability when a compressed HTTP request, with Content-Encoding: gzip, is processed and the corresponding response is not compressed.
This happens because the JDK Inflater is allocated for decompressing the request, but it is not released because the release mechanism is tied to the compressed response.
In this case, since the response is not compressed, the release mechanism does not trigger, causing the leak.

The Jetty URI parser has some key differences to other common parsers when evaluating invalid or unusual URIs. Differential parsing of URIs in systems using multiple components may result in security by-pass. For example a component that enforces a black list may interpret the URIs differently from one that generates a response. At the very least, differential parsing may divulge implementation details.

OpenMQ exposes a TCP-based management service (imqbrokerd) that by default requires
authentication. However, the product ships with a default administrative account (admin/
admin) and does not enforce a mandatory password change on first use. After the first
successful login, the server continues to accept the default password indefinitely without
warning or enforcement.
In real-world deployments, this service is often left enabled without changing the default
credentials. As a result, a remote attacker with access to the service port could authenticate
as an administrator and gain full control of the protocol’s administrative features.
