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 Openfire server in Cisco Finesse Desktop 10.5(1) and 11.0(1) and Unified Contact Center Express 10.6(1) has a hardcoded account, which makes it easier for remote attackers to obtain access via an XMPP session, aka Bug ID CSCuw79085.

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

A hardcoded account exists in the Openfire XMPP server component embedded in Cisco Finesse Desktop 10.5(1), 11.0(1) and Unified Contact Center Express 10.6(1). This hardcoded credential allows remote attackers to authenticate to the XMPP service without proper authorization, potentially gaining access to the contact center messaging infrastructure.

MitigationApply vendor patches for CSCuw79085 when available, remove or disable the hardcoded account, and implement network access controls to limit XMPP service exposure to untrusted networks.

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 the device model
    Log into the device web interface or check the device label to confirm the exact model is Zyxel Gs1900-10hp or Zzinc Keymouse
    Affected if The device is a Zyxel Gs1900-10hp or Zzinc Keymouse
  2. Check the firmware version
    Access the device admin panel and navigate to the firmware or system information page. For Zyxel Gs1900-10hp, look for firmware version < 2.50(aazi.0)c0. For Zzinc Keymouse, look for firmware version = 3.08
    Affected if The installed firmware version matches the affected range (Zyxel: < 2.50(aazi.0)c0, Zzinc: = 3.08)
  3. Verify XMPP service is enabled
    Check the device configuration for Openfire XMPP server settings. Look for XMPP service status in the admin interface or check if port 5222 (default XMPP) is listening on the device
    Affected if The XMPP/Openfire service is enabled and accessible on the device

A user is affected if the device is a Zyxel Gs1900-10hp or Zzinc Keymouse running the specified firmware versions AND the XMPP service is enabled, allowing potential authentication with the hardcoded credential.
