CVE-2018-0483
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 Jabber Client Framework (JCF) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of an affected system. The vulnerability is due to insufficient validation of user-supplied input of an affected client. An attacker could exploit this vulnerability by executing arbitrary JavaScript in the Jabber client of the recipient. A successful exploit could allow the attacker to execute arbitrary script code in the context of the targeted client or allow the attacker to access sensitive client-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 confidenceA cross-site scripting (XSS) vulnerability in Cisco Jabber Client Framework allows an authenticated remote attacker to inject arbitrary JavaScript through insufficient validation of user-supplied input. The attack executes in the context of the victim's Jabber client, enabling access to sensitive client-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.
-
Check if Cisco Jabber is installedSearch for Cisco Jabber in system applications - check Program Files (Windows) or Applications folder (Mac), or look in the Windows registry under HKLM\Software\Cisco Systems\Cisco JabberAffected if Cisco Jabber is not present on the system
-
Identify installed Cisco Jabber versionOpen Cisco Jabber client and navigate to Help > About Cisco Jabber to view version information, or check the jabber-config.xml file, or query the Windows registry key HKLM\Software\Cisco Systems\Cisco Jabber\VersionAffected if Unable to retrieve version information or Jabber is not running
-
Compare version to affected releaseVerify the installed version matches 10.0(0) exactly as listed in the affected versionsAffected if Installed version is 10.0(0) - this version is affected by the XSS vulnerability
-
Assess authentication contextDetermine if users connect to Cisco Jabber servers (XIM, CUCM, or UDS) with authenticated sessions - the vulnerability requires an authenticated attacker to inject malicious JavaScriptAffected if Users have active authenticated Jabber sessions where untrusted or external contacts can send messages
Environment is affected if Cisco Jabber version 10.0(0) is installed and users maintain authenticated Jabber communications where malicious JavaScript could be injected through messages.

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 Cisco security patch for this vulnerability (refer to Cisco advisory) or upgrade to a patched version of Cisco Jabber. Until then, limit trust in authenticated Jabber communications and monitor for suspicious client activity.
