A wrong permission check in KNIME Business Hub before version 1.17.0 allowed an authenticated user to save jobs of other users as if there were saved by the job owner. The attacker must have permissions to access the jobs but then they were saved into the catalog service using the wrong owner permissions. Therefore it may have been possible to save into spaces where the attacker does not have write permissions.
There is no workaround.
Potentially sensitive information in jobs on KNIME Business Hub prior to 1.16.0 were visible to all members of the user's team. Starting with KNIME Business Hub 1.16.0 only metadata of jobs is shown to team members. Only the creator of a job can see all information including in- and output data (if present).
An open redirect vulnerability existed in KNIME Business Hub prior to version 1.16.0. An unauthenticated remote attacker could craft a link to a legitimate KNIME Business Hub installation which, when opened by the user, redirects the user to a page of the attackers choice. This might open the possibility for fishing or other similar attacks. The problem has been fixed in KNIME Business Hub 1.16.0.
