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
Multiple vulnerabilities in the web-based management interface of Cisco UCS Central Software could allow a remote attacker to conduct a cross-site scripting (XSS) attack against a user of the affected interface or hijack a valid session ID from a user of the affected interface. Cisco Bug IDs: CSCvf71978, CSCvf71986.

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

Multiple cross-site scripting (XSS) vulnerabilities and session hijacking flaws exist in the web-based management interface of Cisco UCS Central Software. An authenticated or remote attacker can inject malicious scripts into the interface or capture valid session IDs to impersonate legitimate users.

MitigationApply the Cisco patch for UCS Central Software when available, or implement compensating controls such as restricting management interface access to trusted networks/VPNs and enabling secure session management policies.

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 UCS Central Software version
    Log into the UCS Central management interface and navigate to Admin > System Summary, or use the CLI command 'show version' if available. Alternatively, check the software bundle name displayed in the UCS Central login page or about section.
    Affected if The installed version is exactly 2.2(1a)a
  2. Confirm web-based management interface is enabled
    Access the UCS Central web interface via HTTPS on port 443 or HTTP on port 80. Verify the management interface is reachable by attempting to load the login page.
    Affected if The web management interface is accessible from the network being tested
  3. Check for active management sessions
    Review session management configuration in UCS Central under Admin > Session Management or similar. Inspect whether session IDs are transmitted over unencrypted connections.
    Affected if Session cookies or session IDs can be captured over HTTP, or secure session flags are not enforced

You are affected if Cisco UCS Central Software version 2.2(1a)a is installed AND the web-based management interface is accessible on your network.
