Summary
=======

The package redmine before version 4.2.1-1 is vulnerable to multiple
issues including arbitrary filesystem access, access restriction
bypass, cross-site scripting, arbitrary file upload and information
disclosure.

Resolution
==========

Upgrade to 4.2.1-1.

# pacman -Syu "redmine>=4.2.1-1"

The problems have been fixed upstream in version 4.2.1.

Workaround
==========

None.

Description
===========

- CVE-2021-29274 (cross-site scripting)

Redmine 4.1.x before 4.1.2 allows cross-site scripting (XSS) because an
issue's subject is mishandled in the auto complete tip.

- CVE-2021-30163 (information disclosure)

Redmine before 4.1.2 allows attackers to discover the names of private
projects if issue-journal details exist that have changes to project_id
values.

- CVE-2021-30164 (access restriction bypass)

Redmine before 4.1.2 allows attackers to bypass the add_issue_notes
permission requirement by leveraging the Issues API.

- CVE-2021-31863 (arbitrary filesystem access)

Insufficient input validation in the Git repository integration of
Redmine before 4.2.1 allows Redmine users to read arbitrary local files
accessible by the application server process.

- CVE-2021-31864 (access restriction bypass)

Redmine before 4.2.1 allows attackers to bypass the add_issue_notes
permission requirement by leveraging the incoming mail handler.

- CVE-2021-31865 (arbitrary file upload)

Redmine before 4.2.1 allows users to circumvent the allowed filename
extensions of uploaded attachments.

- CVE-2021-31866 (information disclosure)

Redmine before 4.1.3 allows an attacker to learn the values of internal
authentication keys by observing timing differences in string
comparison operations within SysController and MailHandlerController.

Impact
======

A remote attacker could disclose private information, perform actions
without having the required permissions, or execute arbitrary
JavaScript code by leveraging cross-site scripting.
