CVE-2015-7457
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 · uneditedCross-site scripting (XSS) vulnerability in IBM WebSphere Portal 8.0.x before 8.0.0.1 CF20 and 8.5.x before 8.5.0.0 CF09 allows remote attackers to inject arbitrary web script or HTML via a crafted URL.
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.

The vulnerability exists in versions 8.0.x before CF20 and 8.5.x before CF09, where user-supplied input in URLs is not properly sanitized before being rendered in the browser.

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 IBM WebSphere Portal versionAccess the WebSphere Portal Administration console and navigate to Portal Settings > Version Information, or use the command line versioninfo utility if available in your installationAffected if The installed version is 8.0.0.0, 8.0.0.1, or any 8.0.x version earlier than CF20, or 8.5.0.0 or any 8.5.x version earlier than CF09
-
Determine Cumulative Fix (CF) levelCheck the installed Cumulative Fix pack level through the WebSphere Portal Administration console under Portal Settings > Fixes, or consult the installation logs or IBM Fix Central documentation for your installationAffected if The CF level is earlier than CF20 for version 8.0.x or earlier than CF09 for version 8.5.x
-
Confirm Portal is accessible via HTTP/HTTPSVerify that WebSphere Portal is running and accessible over HTTP or HTTPS protocolsAffected if Portal is exposed via web URLs and user-supplied parameters can be passed through crafted URLs to the server
Your environment is affected if WebSphere Portal version 8.0.x is earlier than CF20 or version 8.5.x is earlier than CF09, and the Portal is web-accessible allowing URL-based user input.
