Threats Tagged 'cve-2026-54211'

CVE-2026-54211 is a critical buffer overflow vulnerability in Tobit Laboratories AG TeamDavid's Webbox application endpoint “//serverClient_close.html”. Authenticated attackers can submit excessively long form data parameters to trigger a server crash causing denial of service. If combined with other vulnerabilities that disclose stack canaries, this flaw could lead to remote code execution and full server compromise. The vulnerability affects versions before Rollout 528, where the vulnerable functionality is disabled by default.

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 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.
