CVE-2026-54214

TeamDavid: Header Injection through the 'cType' URL parameter

Published Aug 7, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to HTTP header injection through the
“cType” URL parameter, which allows arbitrary modification of the
Content-Type header in HTTP responses. Because the parameter does not
properly restrict control characters such as URL-encoded newlines
(“%0a”) or colons, attackers can inject additional headers including
extra Location headers into the server’s response. This results e.g. in
an open redirect vulnerability. 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.
