CVE-2026-54208: CWE-20 Improper input validation in Tobit Laboratories AG TeamDavid
Tobit Laboratories AG TeamDavid's Webbox application before Rollout 528 is vulnerable to arbitrary file write due to improper input validation. This allows unauthenticated attackers to create or modify files on the server with attacker-controlled content, potentially leading to stored cross-site scripting when malicious files are accessed. Starting with Rollout 528 (June 30, 2026), the vulnerable functionality is disabled by default, mitigating the issue.
AI Analysis
Technical Summary
The vulnerability in Tobit Laboratories AG TeamDavid's Webbox application arises from improper input validation (CWE-20) and insufficient access control (CWE-284), enabling unauthenticated attackers to write arbitrary files on the server. This can be exploited to create files containing malicious JavaScript, triggering stored cross-site scripting upon user access. The issue affects versions before Rollout 528, after which the vulnerable functionality is disabled by default.
Potential Impact
An unauthenticated attacker can write arbitrary files to the server, including files with malicious JavaScript code. This can lead to stored cross-site scripting attacks when users access these files, potentially compromising user sessions or executing malicious scripts in users' browsers. The vulnerability is rated high severity with a CVSS 4.0 score of 8.5.
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 this vulnerability is not exposed. No additional patches are indicated; disabling the affected functionality is the recommended remediation.
