CVE-2022-42446
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 · uneditedStarting with Sametime 12, anonymous users are enabled by default. After logging in as an anonymous user, one has the ability to browse the User Directory and potentially create chats with internal users.
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 confidenceIn HCL Sametime 12 and later, anonymous users are enabled by default, allowing unauthenticated actors to log in as anonymous users, browse the User Directory to enumerate internal users, and potentially initiate chat conversations with those users. This constitutes information disclosure and unauthorized communication access.

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.
-
Verify Sametime versionCheck the installed HCL Sametime version to confirm it is 12.0.xAffected if The installed version is 12.0.x (any 12.0 release)
-
Confirm anonymous access settingLocate and inspect the Sametime server configuration files or admin console for the anonymous user access settingAffected if Anonymous user access is enabled in the Sametime configuration
-
Verify User Directory accessibilityCheck the User Directory configuration to determine whether it permits access by unauthenticated (anonymous) usersAffected if The User Directory allows access without authentication
-
Test unauthenticated chat capabilityUsing an unauthenticated browser or client session, attempt to access the Sametime chat interface or initiate a conversation with an internal userAffected if Anonymous users can browse the user list or initiate chat sessions without credentials
A user is affected if they have Sametime 12.0 installed with anonymous access enabled and the User Directory accessible to unauthenticated users, allowing enumeration of internal users and unauthorized chat initiation.

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.
From vendor dataDisable anonymous user access in Sametime 12 configuration if business requirements do not explicitly require it, and restrict access to the User Directory to authenticated users only.
