DescriptionNVD

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.

AnalysisAI

Remote code execution in Eclipse GlassFish allows attackers with administrative access to the Administration Console to execute arbitrary operating system commands as the application service user. The flaw stems from improper input handling in admin panel requests (CWE-94), and while CVSS rates it 9.1 due to scope change and full CIA impact, exploitation requires high privileges (PR:H). …
