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
Buffer overflow in Cybozu Office 9 and 10 before 10.1.0, Mailwise 4 and 5 before 5.1.4, and Dezie 8 before 8.1.1 allows remote authenticated users to execute arbitrary code via e-mail messages.

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 · high confidence

Buffer overflow vulnerability in Cybozu Office, Mailwise, and Dezie allows remote authenticated users to execute arbitrary code via specially crafted e-mail messages. The flaw exists in the email parsing functionality and can be exploited by attackers who have valid credentials to the affected applications.

MitigationUpgrade to Cybozu Office 10.1.0 or later, Mailwise 5.1.4 or later, and Dezie 8.1.1 or later to address the buffer overflow. Since the vulnerability requires authentication, enforce least-privilege access controls and monitor for suspicious email patterns.

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 product
    Check the application's login page, help documentation, or system information for the product name (Office, Mailwise, or Dezie)
    Affected if The product is Cybozu Office, Mailwise, or Dezie
  2. Determine installed version of Cybozu Office
    Access the system administration panel or check the installer/version file. For Office, look in the control panel or about section under version information
    Affected if Version is 9.0 (any patch level) or 10.0.0 through 10.0.2 (inclusive)
  3. Determine installed version of Cybozu Mailwise
    Access the system administration panel or check the installer/version file. For Mailwise, look in the control panel or about section under version information
    Affected if Version is 4.0 (any patch level) or 5.0 through 5.1.3 (inclusive)
  4. Determine installed version of Cybozu Dezie
    Access the system administration panel or check the installer/version file. For Dezie, look in the control panel or about section under version information
    Affected if Version is 8.1.0 or any earlier version through 8.0 (inclusive)
  5. Verify email receiving functionality is enabled
    Check the application's email settings or server configuration to confirm the email parsing module is active and accepting incoming mail
    Affected if Email receiving and parsing is enabled and the version is within the affected ranges

The environment is affected if Cybozu Office version 9.0 or 10.0.0-10.0.2, Mailwise version 4.0 or 5.0-5.1.3, or Dezie version 8.1.0 or earlier is running with email parsing enabled for authenticated users.

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.

dbcve · scoped
Upgrade available Upgrade to a release after 10.0.2
Interim mitigation

Upgrade to Cybozu Office 10.1.0 or later, Mailwise 5.1.4 or later, and Dezie 8.1.1 or later to address the buffer overflow. Since the vulnerability requires authentication, enforce least-privilege access controls and monitor for suspicious email patterns.

Recommended fix High confidence

Cybozu Office 10.1.0+, Mailwise 5.1.4+, or Dezie 8.1.1+ depending on product

  1. 1. Identify which Cybozu product is affected (Office, Mailwise, or Dezie) in your environment
  2. 2. Determine the current installed version of the affected product
  3. 3. For Cybozu Office: upgrade to version 10.1.0 or later
  4. 4. For Cybozu Mailwise: upgrade to version 5.1.4 or later
  5. 5. For Cybozu Dezie: upgrade to version 8.1.1 or later
