EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 73% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Webbox of TeamDavid by Tobit Laboratories AG constructs redirect URLs using user-supplied input, which is appended to the redirect target in a 302 HTTP response. By using URL-encoded characters such as “%2e” (representing a dot), an attacker can manipulate the portion of the URL following the top-level domain (TLD). If a similar, registerable TLD exists (for example, if “.com” is the application’s domain, and “.company” is available for registration), an attacker can craft a URL to redirect users to a malicious “.company” domain. By using URL-encoded line feeds, it becomes possible to insert arbitrary response headers in the server's HTTP response.

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.
