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
A vulnerability in the Zero Touch Provisioning service of the Cisco SD-WAN Solution could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect bounds checks for certain values in packets that are sent to the Zero Touch Provisioning service of the affected software. An attacker could exploit this vulnerability by sending malicious packets to the affected software for processing. When the software processes the packets, a buffer overflow condition could occur and cause an affected device to reload. A successful exploit could allow the attacker to cause a temporary DoS condition while the device reloads. This vulnerability can be exploited only by traffic that is destined for an affected device. It cannot be exploited by traffic that is transiting a device. This vulnerability affects the following Cisco products if they are running a release of the Cisco SD-WAN Solution prior to Release 18.3.0: vBond Orchestrator Software, vManage Network Management Software, vSmart Controller Software. Cisco Bug IDs: CSCvi69914.

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

Buffer overflow vulnerability in the Zero Touch Provisioning (ZTP) service of Cisco SD-WAN Solution due to insufficient bounds checking on packet values. An unauthenticated remote attacker can send malicious packets to affected devices (vBond Orchestrator, vManage, vSmart Controller) causing a buffer overflow that forces the device to reload, resulting in denial of service. Only traffic destined for the device is exploitable, not transit traffic.

MitigationUpgrade to Cisco SD-WAN Release 18.3.0 or later per Cisco Bug CSCvi69914. If immediate upgrade is not feasible, implement network isolation or ACLs to restrict access to the ZTP service port from untrusted sources.

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 Cisco SD-WAN device type
    Determine if the device is a vBond Orchestrator, vManage, vSmart Controller, vEdge Plus, vEdge Pro, or vEdge 100 series device using the device CLI or management interface
    Affected if The device is any of these product types listed in the affected products
  2. Check the installed software version
    Use the device command line or vManage interface to retrieve the firmware/software version. Compare it against the affected version range: vEdge 100/100b/100m devices are affected if version is below 18.3.0; all other listed products are affected at all versions
    Affected if The version is below 18.3.0 for vEdge 100 series, or the device is any vBond, vManage, vSmart, vEdge Plus, or vEdge Pro at any version
  3. Verify if ZTP service is enabled
    Check the device configuration for Zero Touch Provisioning service status using the appropriate CLI command or vManage interface
    Affected if ZTP is enabled on the device - the vulnerability exists in the ZTP service itself
  4. Determine network exposure of ZTP service
    Identify the port used for ZTP and check if it is accessible from untrusted network segments. Review ACLs or firewall rules protecting the device
    Affected if The ZTP service port is reachable from untrusted or external network sources - only traffic destined for the device is exploitable, not transit traffic

The device is affected if it is any of the listed Cisco SD-WAN products, runs a vulnerable version (or any version for vBond/vManage/vSmart/vEdge Plus/Pro), has ZTP enabled, and the ZTP port is accessible from untrusted networks.
