CVE-2023-45721
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 · uneditedInsufficient default configuration in HCL Leap allows anonymous access to directory information.
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 confidenceInsufficient default configuration in HCL Leap allows unauthenticated (anonymous) users to access directory information, potentially exposing sensitive organizational data such as user lists, email addresses, or other directory structures.

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.
-
Determine installed HCL Leap versionAccess the HCL Leap administration interface or check the product installation details to identify the current version numberAffected if The installed version falls within the range >= 1.1 and < 1.1.4
-
Verify authentication settings for directory accessInspect the HCL Leap configuration or security settings related to directory services and anonymous access permissionsAffected if Anonymous or unauthenticated users are permitted to access directory information or retrieve user data through Leap endpoints
-
Check directory API accessibilityTest accessing directory-related API endpoints or pages without providing credentials to determine if they return organizational dataAffected if Directory endpoints respond with user lists, email addresses, or organizational structure data to unauthenticated requests
-
Review anonymous user permissionsExamine the user role and permission configuration to confirm whether anonymous users have been granted access to sensitive directory resourcesAffected if Anonymous or guest users have explicit permissions to view or query directory information
A user is affected if their HCL Leap version is 1.1.x (where x < 4) AND anonymous/unauthenticated access to directory data is permitted in the configuration.

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 · scoped1.1.4
Configure HCL Leap to require authentication for directory access and restrict anonymous access to sensitive resources through proper authentication and authorization settings.
1.1.4 or later
- Upgrade HCL Domino Leap to version 1.1.4 or later to resolve the insufficient default configuration
