Buffer Overflow in TeamDavid Webbox Application

Publication date: 2026-08-07

Last updated on: 2026-08-07

Assigner: Switzerland Government Common Vulnerability Program

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.

Executive Summary

Tobit Laboratories AG TeamDavid's Webbox application has a buffer overflow vulnerability in the endpoint //serverClient_close.html. Authenticated attackers can send excessively long values in form data parameters to crash the server, causing a denial of service. If stack state allows or a stack canary is disclosed via another flaw, this could potentially lead to remote code execution and full server compromise.

Detection Guidance

Detecting this vulnerability requires monitoring for crashes in the TeamDavid Webbox application, particularly when handling long input values in the //serverClient_close.html endpoint. Check server logs for segmentation faults or application crashes during form submissions. Inspect network traffic for unusually large payloads targeting this endpoint.

Impact Analysis

This vulnerability allows authenticated attackers to crash the TeamDavid server, disrupting service availability. In severe cases, it may enable remote code execution, leading to full server compromise and potential data breaches or unauthorized access to sensitive information.

Compliance Impact

This vulnerability could lead to denial of service or potential remote code execution, which may result in unauthorized access to sensitive data. This could violate GDPR's data protection requirements and HIPAA's security and privacy rules if patient or personal data is compromised.

Mitigation Strategies

Immediately update TeamDavid to the latest Rollout version beyond 524. Implement input validation to restrict form parameter lengths. Disable or restrict access to the //serverClient_close.html endpoint if not required. Monitor for crashes and block suspicious traffic patterns.
