Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to a stored XSS vulnerability. An attacker can send an email containing malicious JavaScript code. When a user accesses the email, the 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.
A stored cross-site scripting vulnerability has been identified in Tobit Laboratories AG TeamDavid's Webbox application, affecting versions through Rollout 524. This vulnerability allows an attacker to send an email containing malicious JavaScript. When the recipient accesses the email, the script executes, potentially leading to unauthorized actions or data exposure.
Users are advised to update to the latest version of TeamDavid, as the most recent release appears to address this vulnerability. For organizations, consider placing the TeamDavid web server behind a VPN or reverse proxy that filters requests and blocks access to non-essential endpoints.
