EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 69% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to arbitrary file write, allowing an unauthenticated attacker to create or write into existing files on the server with attacker-controlled content. This is possible because user input is written directly to files without proper validation or restriction on file types. As a result, an attacker can create files (e.g., .htm), containing malicious JavaScript code. When a user accesses a file created in this way, stored cross-site scripting is triggered. This issue affects TeamDavid through Rollout 524.
