CVE-2026-54210: CWE-787 Out-of-bounds write in Tobit Laboratories AG TeamDavid
Tobit Laboratories AG TeamDavid's Webbox application implements various file upload functionalities that are vulnerable to a buffer overflow condition. By specifying an excessively long filename in a file upload request, an unauthenticated attacker can trigger a crash of the server, resulting in a 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.
AI Analysis
Technical Summary
CVE-2026-54210 is a critical buffer overflow vulnerability (CWE-787) in the TeamDavid Webbox application by Tobit Laboratories AG. The flaw arises from insufficient bounds checking on filenames in file upload requests, allowing an unauthenticated attacker to trigger a denial of service via server crash. Additionally, if the stack state is favorable or a stack canary can be disclosed through another vulnerability, this buffer overflow could be exploited for remote code execution, leading to full compromise of the server. The vulnerability affects TeamDavid through Rollout 524. No official fix or patch has been published as of the data provided.
Potential Impact
An unauthenticated attacker can cause a denial of service by crashing the server through a buffer overflow triggered by an excessively long filename in a file upload. Furthermore, the vulnerability may allow remote code execution under certain conditions, which could result in complete server compromise.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the file upload functionality and monitor for abnormal requests with excessively long filenames to reduce risk.
