CVE-2026-54210
CriticalCVSS 9.5Summary
File upload functionalities in the TeamDavid Webbox application are vulnerable to a buffer overflow. Specifying an excessively long filename in a file upload request by an unauthenticated attacker can trigger a crash of the server, resulting in denial of service. Depending on stack state or if a stack canary can be disclosed, this buffer overflow could potentially be exploited for remote code execution, leading to full compromise of the server.
Risk Assessment
The risk includes the possibility of remotely crashing the server without authentication, and in extreme cases, remote code execution and full server compromise, potentially leading to data security breaches.
Recommendation
It is recommended to apply vendor patches and validate filename lengths in upload requests. Also, implement buffer overflow protections.
Original NVD description (English source)
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 through Rollout 524.
