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 web-based GUI of Cisco Integrated Management Controller (IMC) 3.0(1c) could allow an authenticated, remote attacker to perform a cross-site scripting (XSS) attack. The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by persuading an authenticated user of the web-based GUI on an affected system to follow a malicious link. A successful exploit could allow the attacker to execute arbitrary code in the context of the web-based GUI on the affected system. Cisco Bug IDs: CSCvd14587.

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

Cross-site scripting (XSS) vulnerability in Cisco Integrated Management Controller (IMC) web-based GUI version 3.0(1c) due to insufficient validation of user-supplied input. An authenticated attacker can inject malicious scripts via crafted links that execute in the context of the authenticated user's session, potentially allowing arbitrary code execution in the web GUI.

MitigationApply the Cisco patch for bug CSCvd14587 when released; meanwhile, implement robust input validation and output encoding on all user-supplied parameters in the IMC web interface.

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 Cisco IMC product
    Access the web interface or CLI of the Cisco Integrated Management Controller and confirm the product name is Cisco IMC or Cisco Integrated Management Controller
    Affected if The product is not Cisco IMC
  2. Check IMC version
    In the IMC web GUI, navigate to the About or version information page typically found under Admin or Settings. Alternatively, via CLI use 'show version' or 'ucsmcver' command to retrieve the firmware version
    Affected if The installed version is exactly 3.0(1c)
  3. Verify web GUI is accessible
    Confirm the IMC web-based management interface is reachable over HTTPS/HTTP by accessing the IMC IP or hostname in a browser
    Affected if The web GUI is accessible and enabled
  4. Confirm authentication is configured
    Check that local authentication or remote authentication (LDAP/RADIUS) is enabled for IMC access, and valid user credentials exist
    Affected if Authentication is enabled and valid user accounts exist (required for the authenticated XSS attack)

A user is affected if they are running Cisco IMC Supervisor version 3.0(1c) with the web-based GUI accessible and authentication enabled.
