CVE-2018-11786 karaf: SSH RBAC security enforcement
Last modified: 2018-09-21 00:33:23 EDT
As reported by upstream: "A new security advisory has been released for Apache Karaf, that is fixed in recent 4.2.0 release. CVS-2018-11786: Apache Karaf SSH RBAC security enforcement Severity: Moderate Vendor: The Apache Software Foundation Versions Affected: all versions of Apache Karaf prior to 4.2.0.M1 Description: If the sshd service in Karaf is left on so an administrator can manage the running instance, any user with rights to the Karaf console can pivot and read/write any file on the file system to which the Karaf process user has access. This can be locked down a bit by using chroot to change the root directory to protect files outside of the Karaf install directory; it can be further locked down by defining a security manager policy that limits file system access to those directories beneath the Karaf home that are necessary for the system to run. However, this still allows anyone with ssh access to the Karaf process to read and write a large number of files as the Karaf process user. This has been fixed in revision: https://gitbox.apache.org/repos/asf?p=karaf.git;h=24fb477 https://gitbox.apache.org/repos/asf?p=karaf.git;h=7ad0da3 Mitigation: Apache Karaf users should upgrade to 4.2.0.M1 or later as soon as possible.
