Description
Tobit Laboratories AG TeamDavid's Webbox is vulnerable to a local file inclusion vulnerability in the send email, fax, SMS, etc. functionality. By specifying an '@@attach' command in the form field 'scjob', files can be attached to a message, which can then be downloaded by an authenticated user. A filter is in place that restricts access to the David con-fig folder and the user folder. However, this filter can be bypassed by specifying an alternate data stream, allowing the download of sensitive files such as other users' access files containing their passwords or the server's private key. This issue affects TeamDavid through Rollout 524.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-54200 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-54200 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-54200. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-54200 in your dependencies?
O3 detects CVE-2026-54200 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
