{"id":"CVE-2018-11787","aliases":["GHSA-cq9c-55r7-455x"],"url":"https://o3.security/vulnerability/CVE-2018-11787","summary":"Improper Authentication in Apache Karaf","details":"In Apache Karaf version prior to 3.0.9, 4.0.9, 4.1.1, 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.","published":"2018-09-18T14:29:00.620Z","modified":"2026-07-08T17:15:01.795729Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.karaf:apache-karaf","fixedVersion":"3.0.9"},{"ecosystem":"Maven","name":"org.apache.karaf:apache-karaf","fixedVersion":"4.0.9"},{"ecosystem":"Maven","name":"org.apache.karaf:apache-karaf","fixedVersion":"4.1.1"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/d9ba4c3104ba32225646879a057b75b54430f349c246c85469037d3c%40%3Cdev.karaf.apache.org%3E"},{"type":"ADVISORY","url":"https://issues.apache.org/jira/browse/KARAF-4993"},{"type":"FIX","url":"http://karaf.apache.org/security/cve-2018-11787.txt"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T17:15:01.795729Z"}}
