Oracle · Oracle Glassfish Open Source Edition · CVE-2018-14324
**Name of the Vulnerable Software and Affected Versions**
Oracle GlassFish Open Source Edition version 5.0
**Description**
The issue allows remote attackers to obtain potentially sensitive information, perform database operations, or manipulate the demo via a JMX RMI session. This is due to the demo feature having TCP port 7676 open by default with a password of `admin` for the `admin` account.
**Recommendations**
For Oracle GlassFish Open Source Edition version 5.0, change the default password of the `admin` account to prevent unauthorized access. Consider restricting access to TCP port 7676 to minimize the risk of exploitation. As a temporary workaround, consider disabling the demo feature until a more secure configuration can be implemented.
