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.
File attachments in Kanboard are resolved based on the `path` field in the `project_has_files` table of the SQLite database. An attacker with administrator privileges can upload a modified `sqlite.db` file using the dedicated import function, placing path traversal sequences in the `path` field pointing to arbitrary system files. After uploading the modified database and accessing the project page, it is possible to trigger a download of the specified file, resulting in reading of arbitrary files accessible to the Kanboard application process.
An attacker can read arbitrary system files accessible within the Kanboard application's permission context (e.g., configuration files, private keys) and delete files from the server, which may lead to data confidentiality breach and system destabilization.
Kanboard should be updated to version 1.2.42 or later. The vendor does not indicate any workarounds for this vulnerability — the only solution is to update.
