CVE-2026-54210 Details
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.
A buffer overflow vulnerability has been identified in Tobit Laboratories AG TeamDavid's Webbox application, specifically in versions through Rollout 524. The vulnerability arises from various file upload functionalities that allow an unauthenticated attacker to specify excessively long filenames. This leads to a server crash, causing a denial-of-service condition. Furthermore, depending on the state of the stack or if a stack canary can be leaked through another vulnerability, this buffer overflow could potentially be exploited for remote code execution, resulting in full server compromise.
Users are advised to update to the latest version of TeamDavid, as the most recent release appears to address these vulnerabilities. For those unable to update, consider placing the application behind a VPN or reverse proxy that filters requests and blocks access to non-essential endpoints.
