CVE-2026-54210

TeamDavid: Buffer Overflow in file names of file upload functionalities

Published Aug 7, 2026 CVSS 4.0 · 9.5 Critical EPSS < 1% KEV · Not listed
Description
Tobit Laboratories AG TeamDavid's Webbox application implements various file upload functionalities that are
vulnerable to a buffer overflow condition. By specifying an excessively
long filename in a file upload request, an unauthenticated attacker can
trigger a crash of the server, resulting in a denial of service.
Depending on the stack state or if a stack canary can be disclosed
through another vulnerability, this buffer overflow could potentially be
exploited for remote code execution, leading to full compromise of the
server. 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.
