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 mobility extension on Cisco Unified IP 9900 phones with firmware 9.4(.1) and earlier allows remote attackers to obtain sensitive information by sniffing the network, aka Bug ID CSCuq12117.

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 mobility extension on Cisco Unified IP 9900 phones with firmware 9.4(1) and earlier transmits sensitive information in an insecure manner, allowing remote attackers to capture confidential data via network sniffing.

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 phone model
    Access the phone's web interface or check the physical device to confirm it is a Cisco Unified IP Phone 9900 series model
    Affected if Device is not a Cisco Unified IP 9900 series phone - not affected
  2. Check firmware version
    On the phone, go to Settings > Status > Firmware Version, or access the web interface and navigate to Info > Device Information to view the firmware version
    Affected if Firmware version is 9.4(1) or earlier (any version up to and including 9.4(1))
  3. Verify mobility extension status
    Access the phone's web interface and check the mobility extension configuration under Applications > Mobility, or check if the mobility feature is enabled in the phone settings
    Affected if Mobility extension is enabled - vulnerable when combined with affected firmware version

The environment is affected if the device is a Cisco Unified IP 9900 series phone running firmware version 9.4(1) or earlier and the mobility extension feature is enabled, as sensitive data is transmitted insecurely only when this feature is active.
