CVE-2026-54208 PUBLISHED

TeamDavid: Arbitrary File Write leading to Stored XSS

Assigner: NCSC.ch
Reserved: 12.06.2026 Published: 07.08.2026 Updated: 07.08.2026

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.
