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 Small Business 500 Wireless Access Point devices with firmware 1.0.4.4 allow remote attackers to set the system time via a crafted POST request, aka Bug ID CSCuy01457.

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

Cisco Small Business 500 Wireless Access Point devices with firmware 1.0.4.4 contain an improper input validation vulnerability allowing unauthenticated remote attackers to set the system time via a crafted POST request to the management interface.

MitigationUpdate to patched firmware version if available; otherwise restrict management interface access to trusted networks or IP addresses using ACLs or VPN.

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 device model
    Access the device web management interface or check device label/menu to confirm it is a Cisco Small Business 500 Series Wireless Access Point
    Affected if Device is not a Cisco Small Business 500 Series Wireless Access Point
  2. Check firmware version
    Navigate to the device management interface status or system information page, or use SNMP or CLI command to retrieve firmware version (common command: show version or system info)
    Affected if Firmware version is exactly 1.0.4.4
  3. Verify management interface accessibility
    Attempt to access the device management web interface from an external network or check firewall/ACL rules that permit access to the management interface (typically ports 80 or 443)
    Affected if Management interface is reachable from untrusted networks (not restricted by ACLs, VPN, or firewall)

Device is affected only if it is a Cisco Small Business 500 Wireless Access Point running firmware version 1.0.4.4 with its management interface exposed to untrusted networks.
