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 · uneditedOpen-Xchange GmbH OX App Suite 7.8.3 and earlier is affected by: Cross Site Scripting (XSS).
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 confidenceCross-Site Scripting (XSS) vulnerability in Open-Xchange OX App Suite version 7.8.3 and earlier allows attackers to inject malicious scripts through unspecified vectors. The medium severity rating indicates the attack requires user interaction but can be executed remotely without authentication.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify if Open-Xchange OX App Suite is installedCheck for OX App Suite installation via system package manager (rpm -qa | grep -i 'open-xchange' or dpkg -l | grep -i 'open-xchange') or look for OX-specific directories in common installation paths such as /opt/ or /usr/share/Affected if The package or installation directory is found on the system
-
Determine the installed OX App Suite versionRun the appropriate package query command (rpm -qi open-xchange-appsuite or dpkg -s open-xchange-appsuite) or check version files in the OX installation directory if accessibleAffected if The version returned is 7.8.3 or any earlier version (7.x.x where x is less than 3, or any 6.x.x release)
-
Confirm the web interface is accessible and operationalVerify the OX App Suite web portal is accessible by accessing the login URL (typically https://your-server/ox6/ or /appsuite/) via HTTP request to confirm the application is runningAffected if The web interface responds and is accessible to users, making the XSS vector viable
-
Identify user-facing components that handle inputReview OX App Suite configuration for active modules that accept user-supplied data such as the mail compose feature, calendar entries, contact fields, or document sharing featuresAffected if Any of these input-handling features are enabled and accessible to end users
A system is affected if Open-Xchange OX App Suite version 7.8.3 or earlier is installed and the web interface with user input-handling components is accessible.

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 dataImplement proper input validation and output encoding for all user-supplied data. Apply context-aware sanitization and consider implementing Content Security Policy (CSP) headers to mitigate XSS risks.
