XSS

Kanboard Session Lifetime Validation Bypass Vulnerability
CVE-2024-55603 6.5 - Medium - December 19, 2024

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.

XSS

Kanboard 1.2.x Path Traversal Vulnerability in File Attachment Handling
CVE-2024-51747 7.2 - High - November 11, 2024

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.

Directory traversal

Kanboard 1.2.x Arbitrary PHP Code Execution via Language File Manipulation
CVE-2024-51748 7.2 - High - November 11, 2024

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.
