CVE-2018-0386
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 Cisco Unified Communications Domain Manager Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack on an affected system. The vulnerability is due to improper validation of input that is passed to the affected software. An attacker could exploit this vulnerability by persuading a user of the affected software to access a malicious URL. A successful exploit could allow the attacker to access sensitive, browser-based information on the affected system or perform arbitrary actions in the affected software in the security context of the user. Cisco Bug IDs: CSCvh49694.
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 confidenceThis is a reflected XSS vulnerability in Cisco Unified Communications Domain Manager Software caused by improper input validation. An unauthenticated remote attacker can exploit this by tricking a user into visiting a malicious URL, allowing the attacker to execute arbitrary JavaScript in the user's browser context and potentially steal session credentials or perform actions on behalf of the user.

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.
-
Identify if Cisco Unified Communications Domain Manager is deployedReview your environment inventory or network scans for instances of Cisco Unified Communications Domain Manager software. Check for associated services listening on typical web ports.Affected if The product is present in the environment
-
Check the installed version of Cisco Unified Communications Domain ManagerAccess the web management interface or use CLI commands provided by Cisco to query the software version. Compare against the affected range: all versions.Affected if Any version is found (all versions are affected)
-
Identify if Cisco Hosted Collaboration Solution 11.5(1) is deployedReview environment inventory or network scans for Cisco Hosted Collaboration Solution. Query the version through the management interface or CLI.Affected if Version 11.5(1) is found
-
Verify web management interface is accessibleAttempt to access the web interface on typical ports (443, 8443) or check firewall rules and access controls for the management URL.Affected if The web interface is externally or internally accessible without additional authentication barriers (the exploit is reflected via URL)
-
Review web access logs for suspicious URL patternsExamine HTTP access logs for requests containing script tags, javascript:, or other XSS payloads in URL parameters that may indicate exploitation attempts.
You are affected if Cisco Unified Communications Domain Manager (any version) or Cisco Hosted Collaboration Solution version 11.5(1) is deployed and the web management interface is accessible.

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 when available. Until then, implement URL filtering and user education to prevent clicks on suspicious links. Input validation and output encoding should be implemented on all user-supplied data fields.
