Kanboard: >> Kanboard >> 1.2.41 Security Vulnerabilities
Kanboard is project management software that focuses on the Kanban methodology. Versions 1.2.26 through 1.2.44 have a Stored Cross-Site Scripting (XSS) Vulnerability in the `name` parameter of the `http://localhost/?controller=ProjectCreationController&action=create` form. This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. Note that the default content security policy (CSP) blocks the JavaScript attack, though it can be exploited if an instance is badly configured and the software is vulnerable to CSS injection because of the unsafe-inline on the default CSP. Version 1.2.45 contains a fix for the issue.

Kanboard is project management software that focuses on the Kanban methodology. In affected versions sessions are still usable even though their lifetime has exceeded. Kanboard implements a cutom session handler (`app/Core/Session/SessionHandler.php`), to store the session data in a database. Therefore, when a `session_id` is given, kanboard queries the data from the `sessions` sql table. At this point, it does not correctly verify, if a given `session_id` has already exceeded its lifetime (`expires_at`).
Thus, a session which's lifetime is already `> time()`, is still queried from the database and hence a valid login. The implemented **SessionHandlerInterface::gc** function, that does remove invalid sessions, is called only **with a certain probability** (_Cleans up expired sessions. Called by `session_start()`, based on `session.gc_divisor`, `session.gc_probability` and `session.gc_maxlifetime` settings_) accordingly to the php documentation. In the official Kanboard docker image these values default to: session.gc_probability=1, session.gc_divisor=1000. Thus, an expired session is only terminated with probability 1/1000. This issue has been addressed in release 1.2.43 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Kanboard is project management software that focuses on the Kanban methodology. An authenticated Kanboard admin can read and delete arbitrary files from the server. File attachments, that are viewable or downloadable in Kanboard are resolved through its `path` entry in the `project_has_files` SQLite db. Thus, an attacker who can upload a modified sqlite.db through the dedicated feature, can set arbitrary file links, by abusing path traversals. Once the modified db is uploaded and the project page is accessed, a file download can be triggered and all files, readable in the context of the Kanboard application permissions, can be downloaded. This issue has been addressed in version 1.2.42 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Kanboard is project management software that focuses on the Kanban methodology. An authenticated Kanboard admin can run arbitrary php code on the server in combination with a file write possibility. The user interface language is determined and loaded by the setting `application_language` in the `settings` table. Thus, an attacker who can upload a modified sqlite.db through the dedicated feature, has control over the filepath, which is loaded. Exploiting this vulnerability has one constraint: the attacker must be able to place a file (called translations.php) on the system. However, this is not impossible, think of anonymous FTP server or another application that allows uploading files. Once the attacker has placed its file with the actual php code as the payload, the attacker can craft a sqlite db settings, which uses path traversal to point to the directory, where the `translations.php` file is stored. Then gaining code execution after importing the crafted sqlite.db. This issue has been addressed in version 1.2.42 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
