CVE-2026-54200 Details
Description
Tobit Laboratories AG TeamDavid's Webbox is vulnerable to a local file inclusion vulnerability in the send email, fax, SMS, etc. functionality. By specifying an '@@attach' command in the form field 'scjob', files can be attached to a message, which can then be downloaded by an authenticated user. A filter is in place that restricts access to the David con-fig folder and the user folder. However, this filter can be bypassed by specifying an alternate data stream, allowing the download of sensitive files such as other users' access files containing their passwords or the server's private key. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.
A local file inclusion vulnerability has been identified in Tobit Laboratories TeamDavid's Webbox, specifically within the messaging functionality that includes email, fax, and SMS. This vulnerability allows authenticated users to attach files to messages by using the '@@attach' command in the 'scjob' form field. Although there is a filter intended to block access to certain directories, it can be bypassed by exploiting NTFS Alternate Data Streams, enabling the download of sensitive files such as other users' access files containing passwords or the server's private key. This issue affects TeamDavid through Rollout 524.
Users are advised to update to the latest version of TeamDavid, as the most recent release appears to address these vulnerabilities. For organizations, it is recommended to avoid exposing the TeamDavid web server directly to the internet, to restrict outbound connections like SMB, and to rotate credentials due to the application's insecure password storage.
