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
The web-based user interface in Cisco Jabber through 9.6(3) and 9.7 through 9.7(5) on Windows allows remote attackers to obtain sensitive information via a crafted value in a GET request, aka Bug IDs CSCuu65622 and CSCuu70858.

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

The web-based user interface in Cisco Jabber through version 9.6(3) and versions 9.7 through 9.7(5) on Windows contains an information disclosure vulnerability. Remote attackers can obtain sensitive information by sending a crafted value in a GET request to the application, likely due to improper input validation or access control in the web UI component.

MitigationUpgrade Cisco Jabber to version 9.7(6)+ or 9.6(4)+ (or latest available), or apply the relevant Cisco patches for bug IDs CSCuu65622 and CSCuu70858. If upgrading is not immediately feasible, restrict network access to the Jabber web interface.

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. Check if Cisco Jabber is installed on Windows
    Open Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed software and look for Cisco Jabber.
    Affected if Cisco Jabber appears in the installed programs list.
  2. Identify the installed Cisco Jabber version
    In Programs and Features, note the exact version shown (for example 9.6(3), 9.7(5), etc.). Alternatively, right-click the Cisco Jabber desktop shortcut, select Properties, and check the version in the Details tab.
    Affected if The version displayed is exactly 9.6(0), 9.6(1), 9.6(2), 9.6(3), 9.7(0), 9.7(1), 9.7(2), 9.7(3), 9.7(4), or 9.7(5).
  3. Determine if the web UI component is accessible
    Attempt to access the Cisco Jabber web interface by opening a browser and navigating to http://localhost:8080 or the typical Jabber web port used in your environment. Check if the login or status page loads.
    Affected if The web UI responds to HTTP requests, indicating the web component is enabled and reachable.
  4. Verify network exposure of the web interface
    Use netstat -an | findstr LISTENING to list listening ports, or check Windows Firewall rules for Jabber-related inbound rules. Identify if the Jabber web service port is bound to external interfaces (0.0.0.0) rather than localhost only.
    Affected if The Jabber web port listens on all interfaces (0.0.0.0) or firewall rules allow external access.

A user is affected if Cisco Jabber versions 9.6(0) through 9.6(3) or 9.7(0) through 9.7(5) are installed with the web UI component enabled and accessible, exposing the interface to potential information disclosure attacks.
