Arbitrary File Write in TeamDavid's Webbox Application

Publication date: 2026-08-07

Last updated on: 2026-08-07

Assigner: Switzerland Government Common Vulnerability Program

Description
Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to arbitrary file write, allowing an unauthenticated attacker to create or write into existing files on the server with attacker-controlled content. This is possible because user input is written directly to files without proper validation or restriction on file types. As a result, an attacker can create files (e.g., .htm), containing malicious JavaScript code. When a user accesses a file created in this way, stored cross-site scripting is triggered. This issue affects TeamDavid through Rollout 524.

Executive Summary

This vulnerability allows an unauthenticated attacker to write arbitrary files to the server by exploiting improper input validation in Tobit Laboratories AG TeamDavid's Webbox application. Attackers can create or modify files, such as .htm files containing malicious JavaScript, which triggers stored cross-site scripting when accessed.

Detection Guidance

Detecting this vulnerability requires checking for arbitrary file writes in TeamDavid's Webbox application. Inspect server directories for unexpected files, especially .htm files with suspicious JavaScript content. Monitor network traffic for unauthenticated file creation requests. Review server logs for unusual file write operations.

Impact Analysis

An attacker could exploit this to execute malicious scripts in a user's browser, potentially stealing sensitive data, session cookies, or performing actions on behalf of the user. This could lead to unauthorized access, data breaches, or defacement of web content.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information. Organizations may face fines, legal liabilities, and reputational damage due to non-compliance with these regulations.

Mitigation Strategies

Update TeamDavid to a version beyond Rollout 524 where the vulnerability is addressed. Implement strict input validation for file writes and restrict file type permissions to prevent arbitrary file creation.
