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
Cisco Unified Wireless Network (UWN) Solution 7.x before 7.0.98.0 allows remote attackers to cause a denial of service (device crash) by pinging a virtual interface, aka Bug ID CSCte55370.

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

A denial of service vulnerability exists in Cisco Unified Wireless Network Solution 7.x versions before 7.0.98.0. Remote attackers can crash the device by sending ICMP ping packets to a virtual interface, causing the system to become unavailable.

MitigationUpgrade Cisco Unified Wireless Network Solution to version 7.0.98.0 or later to patch this vulnerability. Until the upgrade can be performed, consider implementing network access controls to limit which hosts can reach the virtual interfaces.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 installed Cisco Unified Wireless Network Solution version
    Access the wireless controller CLI and run 'show version' or access the web interface and navigate to the software version information page. Alternatively, check the controller's System > General page in the web interface.
    Affected if The displayed version is 7.0.x where x is less than 98 (for example, 7.0.10.0, 7.0.50.0, 7.0.97.0) indicating the version is before 7.0.98.0.
  2. Determine if virtual interfaces are configured
    Run 'show interface' in the controller CLI to list all configured interfaces. Look for virtual interface entries such as 'redundancy-management', 'AP-manager', or other virtual interfaces.
    Affected if Virtual interfaces are listed and configured on the system.
  3. Verify ICMP access control to virtual interfaces
    Run 'show access-list' or check the ACL configuration on the wireless controller. Specifically examine any ACLs applied to the management or virtual interface that may permit or block ICMP traffic.
    Affected if No ACL is applied to block ICMP traffic to virtual interfaces, or an ACL permits ICMP packets from untrusted/any source addresses.
  4. Check management interface exposure
    Verify the source addresses permitted to ping the management interface by reviewing the controller's management access settings. Use 'show run | include ping' or check the web interface under Management > Access Settings > ICMP Settings.
    Affected if ICMP ping is enabled and accessible from untrusted or any network addresses, not restricted to management VLAN or specific admin subnets.

You are affected if your Cisco Unified Wireless Network Solution version is 7.0.x before 7.0.98.0 AND your virtual or management interfaces accept ICMP ping packets from untrusted network sources.
