CVE-2026-54212: CWE-787 Out-of-bounds write in Tobit Laboratories AG TeamDavid
A critical buffer overflow vulnerability (CWE-787) exists in Tobit Laboratories AG TeamDavid's Webbox application API endpoint. An unauthenticated attacker can submit a specially crafted JSON body, at least 8 characters long and beginning with a number, to cause a denial of service by crashing the server. This vulnerability affects TeamDavid versions before Rollout 528. Starting with Rollout 528 (June 30, 2026), the vulnerable functionality is disabled by default, mitigating exposure.
AI Analysis
Technical Summary
CVE-2026-54212 is a buffer overflow vulnerability in the Webbox API endpoint of Tobit Laboratories AG TeamDavid. The flaw allows an unauthenticated attacker to send a crafted JSON payload (minimum 8 characters, starting with a number) that triggers a server crash (denial of service). The vulnerability could potentially lead to remote code execution if combined with disclosure of stack canaries or favorable stack conditions. The issue affects TeamDavid versions prior to Rollout 528, where the vulnerable functionality is disabled by default, reducing risk.
Potential Impact
Exploitation can cause denial of service by crashing the server. Under certain conditions, such as disclosure of stack canaries, remote code execution and full server compromise may be possible. The vulnerability is rated critical with a CVSS 4.0 score of 9.5, reflecting high impact and network attack vector without privileges or user interaction.
Mitigation Recommendations
Starting with Rollout 528 (June 30, 2026), the vulnerable functionality is disabled by default, effectively mitigating the issue. Users should upgrade to Rollout 528 or later to ensure the vulnerability is not exposed. No other patch or fix links are provided. Until upgrade, avoid exposing the vulnerable API endpoint to untrusted networks.
