CVE-2018-0328 — Cisco Unified Communications Manager security vulnerability

Medium CVSS 6.1

A vulnerability in the web framework of Cisco Unified Communications Manager and Cisco Unified Presence could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web interface of an affected system. The vulnerability is due to insufficient input validation of certain parameters that are passed to the affected software via the HTTP GET and HTTP POST methods. An attacker who can convince a user to follow an attacker-supplied link could execute arbitrary script or HTML code in the user's browser in the context of an affected site. Cisco Bug IDs: CSCvg89116.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
