HTTP Header Injection in TeamDavid's Webbox Application

Publication date: 2026-08-07

Last updated on: 2026-09-07

Assigner: Switzerland Government Common Vulnerability Program

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.

Attack-Flow Graph

Executive Summary

Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to HTTP header injection via the 'cType' URL parameter. This flaw allows attackers to modify the Content-Type header in HTTP responses by injecting control characters like URL-encoded newlines or colons. The vulnerability enables the addition of extra headers, including Location headers, leading to issues such as open redirect attacks.

Detection Guidance

To detect this vulnerability, inspect HTTP responses for improperly modified Content-Type headers or additional Location headers injected via the 'cType' parameter. Use tools like curl to send requests with crafted 'cType' values containing URL-encoded newlines (%0a) or colons to observe header injection. Example: curl -v 'http://target.com/path?cType=text/html%0aLocation:http://malicious.com'

Impact Analysis

This vulnerability could allow attackers to redirect users to malicious websites, potentially leading to phishing attacks, credential theft, or malware infections. It may also enable unauthorized access to sensitive data if combined with other exploits.

Compliance Impact

This vulnerability could lead to data breaches or unauthorized access, violating GDPR's data protection requirements and HIPAA's security rules. Organizations may face fines or penalties for failing to protect user data adequately.

Mitigation Strategies

Immediately update TeamDavid to a version beyond Rollout 524. If an update is unavailable, implement input validation to restrict control characters in the 'cType' parameter. Additionally, configure web application firewalls to block requests containing suspicious header injection patterns like URL-encoded newlines or colons.
