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
Cross-site scripting vulnerability in the specific parameters of Cybozu Office 10.0.0 to 10.8.5 allows a remote attacker to inject an arbitrary script via 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

Cross-site scripting (XSS) vulnerability in Cybozu Office versions 10.0.0 through 10.8.5 allows remote attackers to inject arbitrary JavaScript or HTML via specific parameters that are not properly sanitized or validated before being rendered in the application's web interface.

MitigationApply the vendor patch (Cybozu Office 10.8.6 or later) to properly encode output and sanitize user-supplied input in the affected parameters.

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. Confirm Cybozu Office is installed
    Check for Cybozu Office by reviewing installed applications on the server, typically found in the web server's document root or application directory (commonly under /var/www/html/, /opt/, or C:\inetpub\ on Windows). Look for the 'office' directory or.cybozu.com related folders.
    Affected if Cybozu Office application files exist on the system
  2. Locate the installed version
    Access the Cybozu Office system administrator settings page, or check the version information file typically located in the installation directory. The version may also be visible in the login page footer or system administration panel under 'System information' or 'Version info'.
    Affected if The version displayed cannot be determined or is not visible
  3. Compare your version to the affected range
    Verify the installed version against the affected range: 10.0.0 through 10.8.5. If the detected version is 10.0.0, 10.0.1, 10.1.0, 10.2.0, 10.3.0, 10.4.0, 10.5.0, 10.6.0, 10.7.0, 10.8.0, 10.8.1, 10.8.2, 10.8.3, 10.8.4, or 10.8.5, the system is within the vulnerable range.
    Affected if The installed version is 10.0.0 to 10.8.5 inclusive
  4. Identify accessible web endpoints
    Review web access logs or network configuration to confirm the Cybozu Office web interface is accessible to users. The XSS flaw requires the web interface to be reachable since it exploits parameters passed through HTTP requests.
    Affected if The web interface is accessible externally or to untrusted users

If Cybozu Office is installed with a version between 10.0.0 and 10.8.5 inclusive and its web interface is accessible, the environment is vulnerable to CVE-2022-30604.

dbcve · scoped
Upgrade available Upgrade to a release after 10.8.5
Interim mitigation

Apply the vendor patch (Cybozu Office 10.8.6 or later) to properly encode output and sanitize user-supplied input in the affected parameters.

Recommended fix Moderate confidence

Cybozu Office 10.8.6 or later

  1. Identify the current Cybozu Office version installed in your environment
  2. Check Cybozu's official security advisory page (cs.cybozu.co.jp) or JVN (jvn.jp) for the specific fixed version number
  3. Upgrade Cybozu Office to the fixed version (version 10.8.6 or later based on typical Cybozu patch cadence)
  4. After upgrading, verify the fix by testing the previously affected parameters for XSS vulnerability
  5. Ensure proper testing is completed before deploying to production environments
