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
An information disclosure / elevation of privilege vulnerability in the BlackBerry Workspaces Server could potentially allow an attacker who has legitimate access to BlackBerry Workspaces to gain access to another user's workspace by making multiple login requests to the server.

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 confidence

Improper session handling in BlackBerry Workspaces Server allows an authenticated attacker with legitimate access to exploit the login mechanism through multiple sequential requests, enabling unauthorized access to other users' workspaces by hijacking or circumventing session boundaries.

MitigationApply vendor-provided patch for CVE-2017-9370; until patched, implement aggressive session invalidation policies, enable detailed audit logging of login events, and monitor for anomalous cross-user access patterns.

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 BlackBerry Workspaces Server installation
    Search the system for BlackBerry Workspaces Server components, services, or known installation directories. Check running services for processes related to BlackBerry Workspaces.
    Affected if BlackBerry Workspaces Server is installed and running in the environment
  2. Determine BlackBerry Workspaces version
    Locate version information through the product's admin interface, installation directory metadata, or system information tools. Compare the installed version against the affected range.
    Affected if Any version of BlackBerry Workspaces is installed (all versions are affected)
  3. Verify session management is enabled
    Check the BlackBerry Workspaces admin console or configuration files for session management module settings. Confirm whether session handling features are active.
    Affected if Session management is enabled and active on the server
  4. Inspect session configuration for boundary controls
    Review session configuration files or the admin interface for session boundary settings. Look for settings related to session isolation, token validation, or cross-user access controls.
    Affected if Session boundary controls are present but may be improperly enforced (the vulnerability allows session hijacking/cross-user access)
  5. Review authentication logs for sequential requests
    Examine BlackBerry Workspaces audit or authentication logs for patterns of multiple sequential login attempts from the same source, particularly those resulting in access to different user workspaces.
    Affected if Logs show multiple sequential login requests from a single session resulting in access to different user accounts

If BlackBerry Workspaces Server is installed with session management enabled and audit logs reveal patterns of single sessions accessing multiple user workspaces, the environment is likely affected by CVE-2017-9370.
