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
SQL injection vulnerability in the Cybozu Garoon 3.5.0 to 4.2.6 allows remote authenticated attackers to execute arbitrary SQL commands 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

SQL injection vulnerability in Cybozu Garoon allows authenticated remote attackers to execute arbitrary SQL commands through unspecified vectors. The vulnerability affects versions 3.5.0 through 4.2.6 of the groupware product. Successful exploitation could allow attackers to read, modify, or delete database contents including sensitive application data.

MitigationApply vendor patches by upgrading to Cybozu Garoon version 4.2.7 or later. Prioritize this fix given the HIGH CVSS score and potential for full database compromise.

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 installed Cybozu Garoon version
    Access the Garoon system information page. Typically found at '/g/versionInfo.jsp' or via 'Help > System Information' in the Garoon administration console. Alternatively, check the installation directory for version files or check the login page footer which often displays the version number.
    Affected if The displayed version falls within the range 3.5.0 to 4.2.6 inclusive.
  2. Confirm web interface is accessible
    Verify that the Cybozu Garoon web interface is reachable over the network. Attempt to access the Garoon login page via HTTP/HTTPS at the configured URL.
    Affected if The Garoon login page loads and accepts authentication requests.
  3. Verify authentication mechanism exposure
    Check whether the Garoon authentication system is exposed to the network. Determine if remote user authentication is enabled and users can log in to the application.
    Affected if Remote authenticated access to Garoon is possible, allowing an attacker to reach the vulnerable code path.
  4. Review HTTP response headers for version disclosure
    Use a web proxy or curl to fetch the Garoon login page and inspect the HTTP response headers and page source for exact version numbers.
    Affected if Headers or page content reveals a version number between 3.5.0 and 4.2.6.

Your environment is affected if Cybozu Garoon version 3.5.0 through 4.2.6 is installed AND the web interface is accessible to authenticated users.
