CVE-2017-3829
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 Communications Manager Switches 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. More Information: CSCvc30999. Known Affected Releases: 12.0(0.98000.280). Known Fixed Releases: 11.0(1.23900.3) 12.0(0.98000.180) 12.0(0.98000.422) 12.0(0.98000.541) 12.0(0.98000.6).
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 confidenceA cross-site scripting (XSS) vulnerability exists in the web-based management interface of Cisco Unified Communications Manager Switches. An unauthenticated, remote attacker can inject malicious scripts into the management interface, which will execute in the context of legitimate users' browsers when they access the affected 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 checksWork through these to decide whether this CVE applies to you.
-
Check if the web-based management interface is accessibleAttempt to access the Cisco Unified Communications Manager web interface by navigating to the management URL (typically https://<server>/ccmadmin or https://<server>/ucmadmin) from a browser or using curl/curl to test HTTP/HTTPS responseAffected if The web management interface responds and is reachable from the network
-
Identify the Cisco Unified Communications Manager versionLog into the Cisco Unified Communications Manager server via SSH or console and run the command 'show version' or 'utils system version' to retrieve the installed CUCM version numberAffected if The installed version matches 11.0(1.10000.10) or 11.5(1.10000.6) exactly
-
Verify the web interface is enabledCheck the Cisco Unified Communications Manager service activation via the administration interface or by running 'show process list' or checking the Cisco Tomcat service status to confirm the web-based management service is runningAffected if The Cisco Tomcat or web-based management service is running and accessible
You are affected if the Cisco Unified Communications Manager web management interface is accessible AND the installed version is exactly 11.0(1.10000.10) or 11.5(1.10000.6).

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 dataUpgrade Cisco Unified Communications Manager to one of the fixed releases (11.0(1.23900.3), 12.0(0.98000.180), 12.0(0.98000.422), 12.0(0.98000.541), or 12.0(0.98000.6) or later. If immediate patching is not possible, consider restricting access to the web-based management interface to trusted networks only.
