| CVE-2018-11787: Apache Karaf unsecure access to Gogo shell in the webconsole |
| |
| Severity: Moderate |
| |
| Vendor: The Apache Software Foundation |
| |
| Versions Affected: all versions of Apache Karaf prior to 3.0.9, 4.0.9, 4.1.1. |
| |
| Description: |
| |
| When the webconsole feature is installed in Karaf, it is available at |
| .../system/console and requires authentication to access it. One part |
| of the console is a Gogo shell/console that gives access to the |
| command line console of Karaf via a Web browser, and when navigated to |
| it is available at .../system/console/gogo. Trying to go directly to |
| that URL does require authentication. |
| |
| And optional bundle that some applications use is the Pax Web Extender |
| Whiteboard, it is part of the pax-war feature and perhaps others. |
| When it is installed, the Gogo console becomes available at another |
| URL .../gogo/, and that URL is not secured giving access to the Karaf |
| console to unauthenticated users. |
| |
| A mitigation for the issue is to manually stop/uninstall Gogo plugin |
| bundle that is installed with the webconsole feature, although of |
| course this removes the console from the .../system/console |
| application, not only from the unauthenticated endpoint. One could |
| also stop/uninstall the Pax Web Extender Whiteboard, but other |
| components/applications may require it and so their functionality |
| would be reduced/compromised. |
| |
| This has been fixed in revision: |

| https://gitbox.apache.org/repos/asf?p=karaf.git;h=1fc60d7 |
| |
| Mitigation: Apache Karaf users should upgrade to 3.0.9, 4.0.9, 4.1.1 |
| or later as soon as possible. |
