CVE-2026-54208 Details
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 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.
An arbitrary file write vulnerability has been identified in Tobit Laboratories AG TeamDavid's Webbox application, specifically in versions through Rollout 524. This vulnerability allows an unauthenticated attacker to create or modify files on the server with content controlled by the attacker. The issue arises because user input is directly written to files without adequate validation or restrictions on file types. Consequently, an attacker could, for example, create .htm files containing malicious JavaScript. When a user accesses such a file, it triggers stored cross-site scripting.
Users are advised to update to the latest version of TeamDavid, as the most recent release appears to address this vulnerability. For those unable to update, consider implementing additional input validation measures to restrict file types and prevent the creation of files that could be used for cross-site scripting attacks.
