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 authentication system of Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an unauthenticated, remote attacker to change the password of any user, including administrative users. This vulnerability is due to improper implementation of the password-change process. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow an attacker to access the web UI or API with the privileges of the compromised user.

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

Critical authentication bypass in Cisco SSM On-Prem allowing unauthenticated remote attackers to reset any user password (including admin) via crafted HTTP requests to the password-change endpoint. Successful exploitation grants full web UI/API access with compromised user privileges.

MitigationApply Cisco vendor patch immediately upon release; restrict external network access to SSM On-Prem interfaces until patch is deployed; monitor for unauthorized password changes or anomalous authentication patterns.

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 SSM On-Prem is installed
    Locate the Cisco Smart Software Manager On-Prem installation in your environment. This is typically a dedicated appliance or virtual machine running the Cisco SSM On-Prem software. Check your asset inventory or scan for the product.
    Affected if The product is present in your environment
  2. Identify installed version
    Access the SSM On-Prem web UI or check the appliance CLI for the exact version number. The version is typically displayed in the About section of the web interface or obtainable via 'show version' command on the appliance.
    Affected if The installed version is lower than 8-202112 (for example, 8-202111, 7-202110, or earlier)
  3. Verify password change endpoint exposure
    Confirm the SSM On-Prem web interface is network-accessible, either internally or externally. The vulnerability exists in the password-change endpoint that handles HTTP requests for password resets.
    Affected if The SSM On-Prem interface is reachable over the network and the password reset functionality is enabled
  4. Review logs for password change events
    Inspect SSM On-Prem audit logs and system logs for any unauthorized or unexpected password change events, particularly those originating from unauthenticated sources or occurring outside normal administrative activities.
    Affected if Logs show password changes you did not initiate, especially from unauthenticated or unknown IP addresses

You are affected if Cisco SSM On-Prem is installed and the version is below 8-202112, with the web interface network-accessible.

Interim mitigation

Apply Cisco vendor patch immediately upon release; restrict external network access to SSM On-Prem interfaces until patch is deployed; monitor for unauthorized password changes or anomalous authentication patterns.

Recommended fix High confidence

8-202112 or later

  1. 1. Identify the current version of Cisco Smart Software Manager On-Prem (SSM On-Prem) by accessing the web UI or checking system documentation
  2. 2. Download the fixed release (version 8-202112 or later) from the Cisco Software Download page using valid Cisco service contract credentials
  3. 3. Review Cisco's upgrade documentation for SSM On-Prem to understand prerequisites and procedures
  4. 4. Create a full backup of the current SSM On-Prem configuration and data
  5. 5. Schedule a maintenance window as the upgrade may require downtime
  6. 6. Perform the upgrade following Cisco's official upgrade procedure for SSM On-Prem
  7. 7. After upgrade, verify the new version is running: 8-202112 or later
  8. 8. Validate that all user accounts can authenticate properly with their existing passwords
Caveat Review Cisco release notes for version 8-202112 for any configuration or behavioral changes that may affect your deployment
