CVE-2018-0219
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 · uneditedA vulnerability in the web-based management interface of Cisco Unified Computing System (UCS) Director could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCvg86518.
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 confidenceCross-site scripting (XSS) vulnerability in Cisco UCS Director web-based management interface due to insufficient validation of user-supplied input. An unauthenticated remote attacker can exploit this by tricking a user into clicking a crafted malicious link, allowing execution of arbitrary script code in the user's browser context or access to sensitive browser-based information such as session cookies.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Cisco UCS Director installationLocate the UCS Director installation directory or check system services for 'Cisco UCS Director' or 'ucsd' processes running on the serverAffected if Cisco UCS Director is not installed on the system
-
Identify installed UCS Director versionAccess the UCS Director web interface and navigate to Administration > System > About, or check the installation directory for version files. Compare the version to 6.6.0.0Affected if The installed version is exactly 6.6.0.0 (6.6(0.0))
-
Verify web management interface is enabledCheck if the UCS Director web-based management interface (typically ports 80/443 or custom HTTPS port) is accessible and respondingAffected if The web management interface is exposed and accessible to users or attackers
-
Assess user access to web interfaceReview user access controls and authentication settings for the UCS Director web interface to determine if unauthenticated access is possible or if users can be tricked into clicking external linksAffected if Users can access the web interface or are susceptible to clicking untrusted links
The environment is affected only if Cisco UCS Director version 6.6.0.0 is installed with its web-based management interface accessible to users who could click malicious links.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch from Cisco for CSCvg86518. Until patch deployment, users should avoid clicking untrusted links to the UCS Director management interface. Consider implementing WAF rules to detect and block XSS attack patterns.
