A vulnerability in the ConfD CLI of Cisco Elastic Services Controllers could allow an authenticated, remote attacker to log in to an affected system as the admin user, aka an Insecure Default Administrator Credentials Vulnerability. More Information: CSCvc76661. Known Affected Releases: 2.2(9.76).

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

The Cisco Elastic Services Controller's ConfD CLI has an insecure default administrator credentials vulnerability. An authenticated remote attacker can leverage default admin credentials to gain full administrative access to the affected system through the ConfD CLI interface.

MitigationImmediately change the default admin password on all affected Cisco Elastic Services Controller installations to a strong, unique credential. If patches are available from Cisco, apply them according to vendor guidance.

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 Elastic Services Controller installation
    Identify if Cisco Elastic Services Controller software is installed on the system by checking for the product binaries or running processes related to ESC
    Affected if The software is installed and accessible on the network
  2. Check installed ESC version
    Run the command to display the Cisco Elastic Services Controller version, typically via 'show version' or checking the software release information
    Affected if The installed version matches 2.2(9.76)
  3. Verify ConfD CLI accessibility
    Attempt to access the ConfD CLI interface on the affected system, typically on port 2024 or 2025 for the CLI service
    Affected if The ConfD CLI interface is accessible and responds to authentication attempts
  4. Test default credentials
    Attempt to authenticate to the ConfD CLI using the default admin username with default passwords such as 'admin' or the password set during initial installation
    Affected if Authentication succeeds using the default admin account credentials without having been changed from defaults

A user is affected if Cisco Elastic Services Controller version 2.2(9.76) is installed and the ConfD CLI admin account still uses default credentials that have not been changed from the factory defaults.
