CVE-2025-27404 Details
Description
Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. A vulnerability in versions prior to 2.11.5 and 2.12.13 allows an attacker to craft a URL that, once visited by any user, allows to embed arbitrary Javascript into Icinga Web and to act on behalf of that user. This issue has been resolved in versions 2.11.5 and 2.12.3 of Icinga Web 2. As a workaround, those who have Icinga Web 2.12.2 may enable a content security policy in the application settings.
A DOM-based cross-site scripting vulnerability has been identified in Icinga Web 2 versions prior to 2.12.2. This issue allows an attacker to create a URL that, when visited by a user, embeds arbitrary JavaScript into the application and acts on behalf of that user. The vulnerability arises from insufficient input sanitization, enabling the injection of malicious scripts that can be executed in the context of the user's session.
Users can upgrade to Icinga Web 2.11.5 or 2.12.3 to address this vulnerability. Those on version 2.12.2 can enable a content security policy in the application settings as a temporary workaround.
