EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
