CVE-2019-12715
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 interface of Cisco Unified Communications Manager and Cisco Unified Communications Manager Session Management Edition (SME) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface of the affected software. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected software. 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 affected interface or access sensitive browser-based information.
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 Unified Communications Manager and Cisco Unified Communications Manager Session Management Edition web interface allows unauthenticated remote attackers to inject malicious script code via insufficiently validated user-supplied input, potentially enabling execution in the context of the affected interface or theft of sensitive browser-based information.

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 installed Cisco UCM versionAccess the Cisco UCM admin interface and navigate to About > Licensing, or log into the CLI and run the command 'show version' or 'utils system version'. Record the exact build number displayed.Affected if the displayed build number matches exactly 10.5(2.10000.5), 11.5(1.10000.6), 12.0(1.10000.10), or 12.5(1.10000.22)
-
Confirm web interface is accessibleAttempt to reach the Cisco UCM web interface by accessing the primary hostname or IP address over HTTPS (typically port 8443 or 443). Verify the login page loads successfully.Affected if the web interface responds and displays a login page, indicating it is exposed
-
Cross-reference version against CVE-affected buildsCompare the recorded build number from step 1 against the four vulnerable builds listed in the CVE: 10.5(2.10000.5), 11.5(1.10000.6), 12.0(1.10000.10), 12.5(1.10000.22).Affected if the installed version exactly matches one of these four specific builds
You are affected if your Cisco Unified Communications Manager version matches one of the four specific builds AND the web interface is accessible to network users.
