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 Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to incorrect handling of multiple simultaneous device registrations on Cisco SSM On-Prem. An attacker could exploit this vulnerability by sending multiple device registration requests to Cisco SSM On-Prem. A successful exploit could allow the attacker to cause a DoS condition on an affected device.

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 vulnerability in Cisco Smart Software Manager On-Prem allows an authenticated, remote attacker to cause a denial of service condition. The flaw exists due to incorrect handling of multiple simultaneous device registration requests, which can exhaust resources or crash the affected device when exploited.

MitigationApply the relevant Cisco security patch for CVE-2022-20808 when available. Implement rate limiting on device registration endpoints and monitor for unusual registration patterns as a temporary mitigation until the patch is deployed.

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. Confirm Cisco Smart Software Manager On-Prem is installed
    Identify whether Cisco Smart Software Manager On-Prem is deployed in your environment
    Affected if The product is present and running
  2. Check the installed version
    Retrieve the installed version of Cisco Smart Software Manager On-Prem and compare it to the affected range: version 8 or higher, but earlier than 8-202112
    Affected if Version falls between 8 and 8-202111 inclusive
  3. Verify device registration is accessible
    Confirm the device registration functionality is exposed and accessible to authenticated users
    Affected if Device registration endpoint is accessible to authenticated attackers

If Cisco Smart Software Manager On-Prem version 8 through 8-202111 is running with the device registration feature accessible, the environment is vulnerable to CVE-2022-20808
