Vulnerability in org.glassfish.main.admingui:admingui (CVE-2026-2587)

Summary

Vulnerability in org.glassfish.main.admingui:admingui (CVE-2026-2587). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 8.0.2 or later.

Original description

The description as published by the source.

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.
