Remote Code Execution via EL Injection + CSRF [CVE Reservation for Issue 329]
The Eclipse Foundation is a Common Vulnerabilities and Exposures (CVE) Numbering Authority. This issue it used to request and track the progress of the assignment of a CVE for a vulnerability in the project code for an Eclipse open source project. Vulnerability reported Dec 15 2025 by Camilo G.
Basic information
Project name: Eclipse Glassfish
Project id: {id}
Request type: reservation
Versions affected:
- Eclipse GlassFish 8.0.0 (Windows and Linux)
- Eclipse GlassFish all versions before 7.1.0 (Windows and Linux)
Common Weakness Enumeration:
- {CWE-917}
Common Vulnerability Scoring System: {CVSS 9.6}
Summary:
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.
