CVE-2018-12241
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 · uneditedThe Symantec Security Analytics (SA) 7.x prior to 7.3.4 Web UI is susceptible to a reflected cross-site scripting (XSS) vulnerability. A remote attacker with knowledge of the SA web UI hostname or IP address can craft a malicious URL for the SA web UI and target SA web UI users with phishing attacks or other social engineering techniques. A successful attack allows injecting malicious JavaScript code into the SA web UI client application.

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 Symantec Security Analytics is installedIdentify if the Symantec Security Analytics product is deployed in your environment. Check system inventory, installed software lists, or consult with infrastructure teams.Affected if The product is not installed or this is a different product.
-
Determine the installed versionLocate the version information for your Symantec Security Analytics installation. This is typically available in the product's web UI (often in an About or System Info page), or via command line if you have server access.Affected if You cannot determine the version from your installation.
-
Compare your version to the affected rangeCheck if your installed version falls within >= 7.2.1 and < 7.3.4. If your version is 7.2.1, 7.2.2, 7.2.3, 7.3.0, 7.3.1, 7.3.2, or 7.3.3, it is within the affected range.Affected if Your version is 7.2.1 through 7.3.3 inclusive.
-
Verify the Web UI is accessibleConfirm that the Security Analytics web interface is accessible to users. This XSS vulnerability targets the web UI, so if the UI is not in use or is fully isolated, the attack surface may be reduced.Affected if The web interface is accessible and being used.
You are affected if you have Symantec Security Analytics version 7.2.1 through 7.3.3 running with the web UI accessible.
