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 Elastic Services Controller (ESC) web interface of the Cisco Ultra Services Platform could allow an authenticated, remote attacker to acquire sensitive information. The vulnerability is due to the transmission of sensitive information as part of a GET request. An attacker could exploit this vulnerability by sending a GET request to a vulnerable device. An exploit could allow the attacker to view information regarding the Ultra Services Platform deployment. Cisco Bug IDs: CSCvd76406. Known Affected Releases: 21.0.v0.65839.

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 Elastic Services Controller (ESC) web interface in Cisco Ultra Services Platform transmits sensitive deployment information via GET request parameters. An authenticated attacker can exploit this by sending crafted GET requests to view information about the USP deployment. The vulnerability stems from improper handling of sensitive data in URL query strings, which may also be logged in server/access logs.

MitigationMigrate sensitive operations from GET to POST requests; implement proper data handling to avoid exposing sensitive information in URLs; apply vendor patch when available; review server logs for evidence of exploitation.

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 installed Cisco Ultra Services Platform version
    Locate the USP installation and determine the exact version number. This is typically found in system documentation, software metadata, or via CLI commands such as 'show version' or by checking the software image filename.
    Affected if The installed version is exactly 21.0.v0.65839
  2. Confirm ESC web interface is enabled
    Verify that the Elastic Services Controller (ESC) web interface is accessible and enabled on the affected system. This is typically accessible via HTTPS on a configured web port.
    Affected if ESC web interface is enabled and accessible to users
  3. Review server and access logs for sensitive data in URLs
    Examine web server logs, access logs, and application logs for any entries containing sensitive deployment information in URL query strings. Look for parameters that may expose USP deployment details.
    Affected if Logs contain sensitive deployment information visible in GET request URL parameters

User is affected if running exactly version 21.0.v0.65839 of Cisco Ultra Services Platform with the ESC web interface enabled and accessible.
