CVE-2026-54210: CWE-787 Out-of-bounds write in Tobit Laboratories AG TeamDavid
A buffer overflow vulnerability exists in Tobit Laboratories AG TeamDavid's Webbox application due to improper handling of excessively long filenames during file upload. This can cause a server crash resulting in denial of service. Exploitation could potentially lead to remote code execution and full server compromise if certain conditions are met. The vulnerability affects versions before Rollout 528, where the vulnerable functionality is disabled by default.
AI Analysis
Technical Summary
Tobit Laboratories AG TeamDavid's Webbox application has a buffer overflow (CWE-787) triggered by an unauthenticated attacker specifying an excessively long filename in a file upload request. This leads to a denial of service via server crash. Under specific conditions, such as disclosure of a stack canary, the overflow may be exploited for remote code execution. The issue affects TeamDavid versions prior to Rollout 528. Starting with Rollout 528 (June 30, 2026), the vulnerable functionality is disabled by default, mitigating exposure.
Potential Impact
An unauthenticated attacker can cause a denial of service by crashing the server through a buffer overflow triggered by a long filename in file upload. Additionally, if other vulnerabilities allow disclosure of stack canaries or favorable stack state, remote code execution and full server compromise are possible. The vulnerability is rated critical with a CVSS 4.0 score of 9.5.
Mitigation Recommendations
Starting with Rollout 528 (June 30, 2026), the vulnerable file upload functionality is disabled by default, mitigating the issue. Users should upgrade to Rollout 528 or later to ensure this protection. No official patch links are provided; however, disabling the affected functionality is the recommended mitigation.
