The manufacturer describes the product as follows (see [1]): "In-app & Desktop Notifications for Jira app allows you to get all of Jira's email notifications in front of you. Now you won't have to search through all your emails to check for a specific event in Jira, but all what you need to do is to check the notification section in Jira and see all events that happened in Jira and are related to you. You will also receive instant Desktop notifications as well as you will be able to add comments to the tickets directly from the notification." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: It is possible to view all projects within Jira without authentication/authorization. Furthermore it is possible to view all projects within Jira as a logged in user even though no permission was granted to these projects. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): Using the following path it is possible to see all existing projects unauthenticated: /plugins/servlet/nfj/ProjectFilter?searchQuery= To see all projects authenticated, use the following path as logged in user: /plugins/servlet/nfj/NotificationSettings ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: Before delivering a reply, it should be checked whether a request has the necessary authorization. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclosure Timeline: 2019-09-10: Vulnerability discovered 2019-09-24: Vulnerability reported to manufacturer 2019-10-01: Patch released by manufacturer 2019-10-23: Public disclosure of vulnerability ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ References: [1] Product website for In-App & Desktop Notification for Jira https://marketplace.atlassian.com/apps/1217434/in-app-desktop-notifications-for-jira [2] SySS Security Advisory SYSS-2019-042 https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2019-042.txt [3] SySS Responsible Disclosure Policy https://www.syss.de/en/news/responsible-disclosure-policy/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Credits: This security vulnerability was found by Erik Steltzner, Fabian Krone and Sascha Heider of SySS GmbH.
