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
Internet passwords stored in Person documents in the Domino® Directory created using the "Add Person" action on the People & Groups tab in the Domino® Administrator are secured using a cryptographically weak hash algorithm. This could enable attackers with access to the hashed value to determine a user's password, e.g. using a brute force attack. This issue does not impact Person documents created through user registration https://help.hcltechsw.com/domino/10.0.1/admin/conf_userregistration_c.html .

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

Internet passwords in HCL Domino Person documents created via the 'Add Person' action in Domino Administrator are hashed using a cryptographically weak algorithm. Attackers with access to the stored hashes could potentially recover passwords through brute force attacks. This does not affect Person documents created through the user registration process.

MitigationUse the user registration feature instead of the 'Add Person' action for creating Person documents.等待官方补丁修复弱哈希算法问题。

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. Verify Domino version is within affected range
    Check the installed HCL Domino version. On the Domino server console or in Domino Administrator, look at the server document or use 'show version' command. Confirm the version is >= 9.0 and < 14.0.
    Affected if Installed version falls within 9.0 <= version < 14.0
  2. Identify Person documents in the directory
    Access the Domino Directory (names.nsf) and locate Person documents. In Domino Administrator, browse the Directory > People view, or query the Domino Directory database for all documents with form type 'Person'.
    Affected if Person documents exist in the Domino Directory database
  3. Determine creation method of Person documents
    Examine how each Person document was created. Check the document properties or flags that distinguish 'Add Person' action creation from the standard user registration process. Look for a marker, flag, or field that indicates whether the document was created via Domino Administrator's 'Add Person' action versus the user registration feature.
    Affected if Person documents were created using Domino Administrator's 'Add Person' action rather than the user registration process
  4. Inspect password hash algorithm used
    For Person documents identified as created via 'Add Person' action, examine the password hash stored in the internetPassword field or similar password field. Check the cryptographic algorithm used - look for weak hashing indicators such as older hash formats, shorter hash outputs, or lack of salt.
    Affected if Password hashes use a cryptographically weak algorithm (weaker than current Domino registration defaults)
  5. Assess exposure risk
    Determine if attackers could access the stored password hashes. Check file system permissions on names.nsf and the data directory, review who has administrative access, and evaluate whether the Domino Directory database is replicated or accessible externally.
    Affected if The password hash storage is accessible to unauthorized users who could perform offline brute force attacks

User is affected if running Domino 9.0-14.0 and has Person documents created via Domino Administrator's 'Add Person' action with weak password hashing that could be accessed by attackers for brute force recovery.

Recommended fix High confidence

HCL Domino 14.0 or later

  1. Upgrade HCL Domino server to version 14.0 or later to resolve the weak password hashing vulnerability
  2. After upgrade, verify that new Person documents created via 'Add Person' use strong password hashing
  3. For existing affected Person documents, consider re-creating them through user registration (which uses strong hashing) or implementing additional access controls
