CVE-2026-54209 — TeamDavid: Buffer Overflow in 'editini' function
Tobit Laboratories AG TeamDavid's Webbox application handles password changes using a function triggered by including the string "(editini)" in the file path, writing the new password to the specified "Archive.ini" file. However, the application does not verify that the provided path actually refers to an "Archive.ini" file. If an attacker specifies a different file with excessive size, a buffer overflow occurs. This vulnerability allows an unauthenticated attacker to crash the server, resulting in denial of service. 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.
