CVE-2021-32746 Information

Description

Icinga Web 2 is an open source monitoring web interface framework and command-line interface. Between versions 2.3.0 and 2.8.2 the doc module of Icinga Web 2 allows to view documentation directly in the UI. It must be enabled manually by an administrator and users need explicit access permission to use it. Then by visiting a certain route it is possible to gain access to arbitrary files readable by the web-server user. The issue has been fixed in the 2.9.0 2.8.3 and 2.7.5 releases. As a workaround an administrator may disable the doc module or revoke permission to use it from all users.
