Tobit Laboratories AG TeamDavid's Webbox contains an open redirect vulnerability via the “replyUrl” parameter. An attacker can exploit this vulnerability to craft a URL within the application that, when visited, redirects the user’s browser to an arbitrary third-party site. This can be abused for phishing attacks, where users receive a trusted domain link but are redirected to a phishing website. This issue affects TeamDavid through Rollout 524.

All versions through Rollout 524 are affected per the CPE listing. …

Vulnerability AssessmentAI
| Exploitation | The 'replyUrl' parameter in TeamDavid's Webbox component is reachable without authentication (PR:N in the CVSS 4.0 vector), meaning no login or session token is required to craft the malicious URL. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.3 (Medium) accurately captures the constrained direct impact: the flaw enables phishing enablement rather than server-side code execution or data exfiltration. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade TeamDavid to a rollout version beyond Rollout 524 by consulting the vendor release notes at https://david.tobit.software/releasenotes to confirm the exact patched build. … Detailed patch versions, workarounds, and compensating controls in full report. |
