NVD · unedited
Zoho ManageEngine O365 Manager Plus before Build 4416 allows remote code execution via BCP file overwrite through the ChangeDBAPI component.

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

Zoho ManageEngine O365 Manager Plus versions before Build 4416 contain a vulnerability in the ChangeDBAPI component that allows remote attackers to achieve arbitrary code execution by overwriting BCP (Bulk Copy Program) files. The vulnerability allows an authenticated attacker to manipulate file paths used by the database utility to inject and execute malicious code on the affected system.

MitigationUpgrade O365 Manager Plus to Build 4416 or later. If immediate patching is not feasible, restrict network access to the management interface to trusted administrators only and monitor for suspicious file activity in the application's data directories.

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 if O365 Manager Plus is installed
    Locate the ManageEngine O365 Manager Plus installation directory, typically found under the ManageEngine installation folder or C:\Program Files\ManageEngine\ by default on Windows systems. Look for the product executable or service.
    Affected if The software is present on the system.
  2. Determine the installed build version
    Access the O365 Manager Plus admin console and navigate to the About or Help section to view the build number. Alternatively, check the product's version file in the installation directory if accessible.
    Affected if The build number is below 4416, or the version displays as 4.4 without a build number above 4416.
  3. Verify the ChangeDBAPI component is accessible
    Check if the ChangeDBAPI endpoint or interface is reachable on the O365 Manager Plus server. This is typically accessed through the application's web interface or API.
    Affected if The ChangeDBAPI component is exposed and accessible without additional authentication beyond the application login.
  4. Review application authentication exposure
    Determine if the O365 Manager Plus login page is exposed to untrusted networks. Check network firewall rules and access control lists for the management interface port.
    Affected if The application is accessible from untrusted network segments or the internet without proper access restrictions.

If O365 Manager Plus is installed with a version 4.4 or any build below 4416, and the ChangeDBAPI component is accessible to authenticated users, the environment is vulnerable to CVE-2021-44652.
