Icinga Director is an Icinga config deployment tool. A Security vulnerability has been found starting in version 1.0.0 and prior to 1.10.3 and 1.11.3 on several director endpoints of REST API. To reproduce this vulnerability an authenticated user with permission to access the Director is required (plus api access with regard to the api endpoints). And even though some of these Icinga Director users are restricted from accessing certain objects, are able to retrieve information related to them if their name is known. This makes it possible to change the configuration of these objects by those Icinga Director users restricted from accessing them. This results in further exploitation, data breaches and sensitive information disclosure. Affected endpoints include icingaweb2/director/service, if the host name is left out of the query; icingaweb2/directore/notification; icingaweb2/director/serviceset; and icingaweb2/director/scheduled-downtime. In addition, the endpoint icingaweb2/director/services?host=filteredHostName returns a status code 200 even though the services for the host is filtered. This in turn lets the restricted user know that the host filteredHostName exists even though the user is restricted from accessing it. This could again result in further exploitation of this information and data breaches. Icinga Director has patches in versions 1.10.3 and 1.11.1. If upgrading is not feasible, disable the director module for the users other than admin role for the time being.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
There are many different kinds of mistakes that introduce information exposures. The severity of the error can range widely, depending on the context in which the product operates, the type of sensitive information that is revealed, and the benefits it may provide to an attacker. Some kinds of sensitive information include:
Information might be sensitive to different parties, each of which may have their own expectations for whether the information should be protected. These parties include:
Information exposures can occur in different ways:
It is common practice to describe any loss of confidentiality as an “information exposure,” but this can lead to overuse of CWE-200 in CWE mapping. From the CWE perspective, loss of confidentiality is a technical impact that can arise from dozens of different weaknesses, such as insecure file permissions or out-of-bounds read. CWE-200 and its lower-level descendants are intended to cover the mistakes that occur in behaviors that explicitly manage, store, transfer, or cleanse sensitive information.
