CVE-2026-54211
Tobit Laboratories AG TeamDavid's Webbox application’s endpoint “//serverClient_close.html” is vulnerable to a buffer overflow vulnerability in multiple form data parameters.
Overview
CVE-2026-54211 is a known-severity vulnerability. It was published on August 7, 2026.
Technical description
Tobit Laboratories AG TeamDavid's Webbox application’s endpoint “//serverClient_close.html” is vulnerable to a
buffer overflow vulnerability in multiple form data parameters. By
submitting excessively long values in these parameters, an authenticated
attacker can trigger a server crash, resulting in 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 through Rollout 524.
