CVE-2019-1930
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 · uneditedMultiple vulnerabilities in the RSS dashboard in the web-based management interface of Cisco Firepower Management Center (FMC) 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. The vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface of the affected device. An attacker could exploit these vulnerabilities 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 confidenceMultiple reflected XSS vulnerabilities in the RSS dashboard of Cisco Firepower Management Center's web-based management interface allow unauthenticated remote attackers to inject malicious scripts via crafted URLs. The vulnerabilities stem from insufficient validation of user-supplied input in the web 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.
-
Confirm Cisco Firepower Management Center is installedIdentify if the Cisco FMC appliance or virtual machine is deployed in your environment. This is typically a dedicated appliance or VM with a web-based management interface accessible via HTTPS on port 443.Affected if You are running Cisco FMC as your firewall management solution
-
Check the FMC software versionLog into the web-based management interface and navigate to System > Updates, or use the CLI command 'show version' to obtain the installed software version number.Affected if The installed version is exactly 6.2.3, 6.3.0, 6.4.0, or 6.5.0
-
Verify the web management interface is accessibleConfirm the FMC web interface is reachable on the network. The RSS dashboard vulnerability is exploitable through the web UI, so accessibility is required for the flaw to be triggered.Affected if The FMC web interface is network-accessible (even internally)
-
Identify RSS dashboard exposureThe RSS dashboard is a component within the FMC web-based management interface. Check if the dashboard functionality is available or if there are any HTTP access logs showing requests to RSS-related endpoints.Affected if The RSS dashboard feature is present and accessible in the web interface
You are affected if Cisco Firepower Management Center is running and the installed version matches exactly 6.2.3, 6.3.0, 6.4.0, or 6.5.0 with the web interface accessible.
