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 ADManager Plus versionAccess the admin console, navigate to About or Help section to view the build version, or check the installation directory for version filesAffected if Version is 7.1 or below (build 7111 or earlier) based on the affected versions < 7.1 and = 7.1
-
Verify PasswordExpiry interface availabilityCheck if the PasswordExpiry or password expiration feature is enabled in the admin console under the appropriate reporting or management moduleAffected if The PasswordExpiry interface is accessible to authenticated users
-
Confirm authentication is enabledVerify that user authentication is configured and active for the ADManager Plus applicationAffected if Authentication is enabled, allowing users to log in (required for post-authentication exploitation)
-
Check file upload functionalityExamine if file upload capability exists within the PasswordExpiry or related reporting featureAffected if File uploads can be performed through the PasswordExpiry interface by authenticated users
A user is affected if their ManageEngine ADManager Plus installation is version 7.1 or below AND the PasswordExpiry interface with file upload functionality is accessible to 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 · scoped7.1
Apply the vendor patch or upgrade to a fixed build; implement strict file upload validation (file type, extension, content validation) and restrict upload functionality to necessary operations only.
Version 7.2 or later (contact ManageEngine for exact latest stable build)
- 1. Identify the current installed version of ManageEngine ADManager Plus by checking the About or version information in the admin console
- 2. Confirm the build number - if running build 7111 or any version 7.1 or earlier, the system is vulnerable
- 3. Contact ManageEngine official support or visit their download portal to obtain the latest stable release
- 4. Before upgrading, perform a full backup of the ADManager Plus installation directory and database
- 5. Schedule a maintenance window as the upgrade will require service downtime
- 6. Install the upgraded version (version 7.2 or later) following ManageEngine's standard upgrade documentation
- 7. After upgrade, verify the PasswordExpiry interface functionality and confirm the new build number
