Atlassian rates the severity level of this vulnerability as critical.
Information
This advisory discloses a critical severity security vulnerability which was introduced in version 5.3.0 of Jira Service Management Server and Data Center. The following versions are affected by this vulnerability:
5.3.0
5.3.1
5.3.2
5.4.0
5.4.1
5.5.0
An authentication vulnerability was discovered in Jira Service Management Server and Data Center which allows an attacker to impersonate another user and gain access to a Jira Service Management instance under certain circumstances. With write access to a User Directory and outgoing email enabled on a Jira Service Management instance, an attacker could gain access to signup tokens sent to users with accounts that have never been logged into. Access to these tokens can be obtained in two cases:
If the attacker is included on Jira issues or requests with these users, or
If the attacker is forwarded or otherwise gains access to emails containing a “View Request” link from these users.
Bot accounts are particularly susceptible to this scenario. On instances with single sign-on, external customer accounts can be affected in projects where anyone can create their own account.

Atlassian rates the severity level of this vulnerability as critical.
Information
This advisory discloses a critical-severity security misconfiguration vulnerability, which was introduced in Crowd 3.0.0. All versions released after 3.0.0 are affected but only if both of the following conditions are met:
the vulnerability concerns only new installations of affected versions: if you upgraded from an earlier version, for example version 2.9.1, to version 3.0.0 or later, your instance is not affected.
A new installation is defined by an instance of Crowd that is the same version that you originally downloaded from the downloads page and has not been upgraded since
an IP address has been added to the Remote Address configuration of the crowd application (which is none by default in versions after 3.0.0)
The vulnerability allows an attacker connecting from IP in the allow list to authenticate as the crowd application through bypassing a password check. This would allow the attacker to call privileged endpoints in Crowd’s REST API under the usermanagement path.

Information
A Servlet Filter is Java code that intercepts and processes HTTP requests before a client request is sent to a back end resource. They’re also used to intercept and process HTTP responses from a back end resource before they’re sent to a client. Some Servlet Filters provide security mechanisms such as logging, auditing, authentication, or authorization.

Information
When the Questions for Confluence app is enabled on Confluence Server or Data Center, it creates a Confluence user account with the username disabledsystemuser. This account is intended to aid administrators that are migrating data from the app to Confluence Cloud. The disabledsystemuser account is created with a hardcoded password and is added to the confluence-users group, which allows viewing and editing all non-restricted pages within Confluence by default. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access any pages the confluence-users group has access to.
Affected products
Questions For Confluence app for:
- Confluence Server
- Confluence Data Center

Information
A full-read server-side request forgery exists in Mobile Plugin for Jira, which is bundled with Jira and Jira Service Management. It is exploitable by any authenticated user (including a user who joined via the sign-up feature). It specifically affects the batch HTTP endpoint used in Mobile Plugin for Jira. It is possible to control the HTTP method and location of the intended URL through the method parameter in the body of the vulnerable endpoint.

Description
A vulnerability has been identified affecting multiple Atlassian products where special characters, known as Unicode bidirectional override characters, are not rendered or displayed in the affected applications. These special characters are typically not displayed by the browser or code editors but can affect the meaning of the source code when it is processed by a compiler or an interpreter.

Insight – Asset Management app
Jira Service Management Data Center and Server
Description
Insight – Asset Management has a feature to import data from several databases (DBs). One of these DBs, the H2 DB, has a native function in its library which an attacker can use to run code on the server (remote code execution a.k.a. RCE). The H2 DB is bundled with Jira to help speed up the setup of Jira test environments.
The combination of the DB import feature introduced by Insight – Asset Management with the existing Jira H2 DB library exposed this vulnerability. The vulnerability exists whether or not the import configuration was saved and even if H2 was never used as a targeted DB. Accessing this vulnerability requires the following:
The user must be an authenticated Jira user AND
Either of the following privileges within Insight – Asset Management:
- user or group permission to “Insight administrator”
- user or group permission to “Object Schema Manager”
