Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Rumpus - FTP server version 9.0.7.1 has a Reflected cross-site scripting (RXSS) vulnerability through unspecified vectors.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Rumpus FTP server version 9.0.7.1 contains a reflected cross-site scripting (RXSS) vulnerability in its web interface. Attackers can inject malicious scripts through unspecified vectors, which are then reflected back to victim users. This allows session hijacking, credential theft, or defacement of the web interface.

MitigationImplement input validation and output encoding across all user-supplied parameters in the web interface. Deploy Content Security Policy (CSP) headers and ensure the web application uses HttpOnly and Secure flags for session cookies.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Rumpus FTP server version
    Check the installed version of Maxum Rumpus FTP server. This can typically be found in the application itself (Help > About), the installer file properties, or by querying the running service if accessible.
    Affected if The installed version is 9.0.7.1 or any version lower than 9.0.7.1 (any version <= 9.0.7.1).
  2. Verify web interface is enabled
    Confirm that the Rumpus web interface is enabled and accessible. This is typically accessed via HTTP/HTTPS on a configured port (default often 8080 or 2000). Check the Rumpus server configuration for web interface settings.
    Affected if The web interface is enabled and exposed to users or network attackers.
  3. Check for active web sessions
    Inspect whether users are actively using or likely to use the web interface for file transfers or administration. Review server logs for web interface access patterns.
    Affected if Users access the web interface, as RXSS requires victim interaction to execute malicious scripts.

A user is affected if they run Maxum Rumpus version 9.0.7.1 or lower AND have the web interface enabled, as this provides the attack surface for reflected XSS injection.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 9.0.7.1
Interim mitigation

Implement input validation and output encoding across all user-supplied parameters in the web interface. Deploy Content Security Policy (CSP) headers and ensure the web application uses HttpOnly and Secure flags for session cookies.
