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 implements an API endpoint that is vulnerable to a buffer overflow condition. By submitting a specially crafted JSON body, such as one that is at least 8 characters long and begins with a number, an unauthenticated attacker can cause the server to 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 lead to remote code execution and full compromise of the server. This issue affects TeamDavid through Rollout 524.

Executive Summary

Tobit Laboratories AG TeamDavid's Webbox application has an API endpoint vulnerable to a buffer overflow. An unauthenticated attacker can send a specially crafted JSON body (at least 8 characters long starting with a number) to crash the server, causing denial of service. If stack state allows or a canary is bypassed, this could lead to remote code execution and full server compromise.

Detection Guidance

Detecting this vulnerability requires monitoring for crashes in the TeamDavid's Webbox application when processing JSON inputs. Check server logs for unexpected terminations or segmentation faults after sending JSON payloads. Use network traffic analysis tools like Wireshark to inspect incoming JSON requests to the vulnerable API endpoint.

Impact Analysis

This vulnerability allows attackers to crash your TeamDavid Webbox server, disrupting services. In severe cases, it could enable remote code execution, letting attackers take full control of your server, steal data, or install malware.

Compliance Impact

A successful attack could lead to data breaches, violating GDPR (data protection) and HIPAA (health data privacy). This may result in legal penalties, fines, and reputational damage due to unauthorized access to sensitive information.

Mitigation Strategies

Immediately update TeamDavid to a version beyond Rollout 524 to patch the buffer overflow. If an update is unavailable, restrict network access to the vulnerable API endpoint using firewalls or network segmentation. Monitor server logs for exploitation attempts and consider disabling the API if not essential.
