CVE-2023-33956 Detail

Description

Kanboard is open source project management software that focuses on the Kanban methodology. Versions prior to 1.2.30 are subject to an Insecure direct object reference (IDOR) vulnerability present in the application's URL parameter. This vulnerability enables any user to read files uploaded by any other user, regardless of their privileges or restrictions. By Changing the file_id any user can render all the files where MimeType is image uploaded under **/files** directory regard less of uploaded by any user. This vulnerability poses a significant impact and severity to the application's security. By manipulating the URL parameter, an attacker can access sensitive files that should only be available to authorized users. This includes confidential documents or any other type of file stored within the application. The ability to read these files can lead to various detrimental consequences, such as unauthorized disclosure of sensitive information, privacy breaches, intellectual property theft, or exposure of trade secrets. Additionally, it could result in legal and regulatory implications, reputation damage, financial losses, and potential compromise of user trust. Users are advised to upgrade. There are no known workarounds for this vulnerability.

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
