CVE-2017-12258
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 UI of Cisco Unified Communications Manager could allow an unauthenticated, remote attacker to execute a cross-frame scripting (XFS) attack. The vulnerability exists because the affected software does not provide sufficient protections for HTML inline frames (iframes). An attacker could exploit this vulnerability by directing a user of the affected software to an attacker-controlled web page that contains a malicious HTML inline frame. A successful exploit could allow the attacker to conduct click-jacking or other types of client-side browser attacks. Cisco Bug IDs: CSCve60993.
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-frame scripting (XFS) vulnerability in Cisco Unified Communications Manager web-based UI allows attackers to embed malicious iframes from attacker-controlled pages. Insufficient iframe protections enable click-jacking and other client-side browser attacks by tricking authenticated users into interacting with hidden or disguised interface elements.

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 Unified Communications Manager is installedCheck for the presence of the Cisco Unified Communications Manager application or service on the system. Look for processes named 'Cisco Unified Communications Manager' or check installed programs list.Affected if The product is present on the system
-
Verify the web-based UI is accessibleAttempt to access the Cisco Unified Communications Manager web interface via HTTP/HTTPS from the system or a test machine to confirm it responds.Affected if The web UI responds to requests and is network-accessible
-
Check for X-Frame-Options response headerSend an HTTP GET request to the web UI login page or any authenticated page and inspect the response headers for the presence of 'X-Frame-Options: DENY' or 'X-Frame-Options: SAMEORIGIN'.Affected if The X-Frame-Options header is missing or set to a weak value like ALLOW-FROM an untrusted origin
-
Check for Content Security Policy frame-ancestors directiveInspect the HTTP response headers for 'Content-Security-Policy' and verify if the 'frame-ancestors' directive is present and restricts framing to trusted origins.Affected if No CSP frame-ancestors directive is defined or it allows arbitrary origins
The environment is affected if Cisco Unified Communications Manager web UI is running and lacks X-Frame-Options and CSP frame-ancestors protections, allowing untrusted sites to embed the interface in iframes.

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 dataAdd X-Frame-Options: DENY or SAMEORIGIN response headers and/or implement Content Security Policy with frame-ancestors directive to restrict which origins can embed the application in iframes.
