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 · unedited
Rapid7 Nexpose is vulnerable to a non-persistent cross-site scripting vulnerability affecting the Security Console's Filtered Asset Search feature. A specific search criterion and operator combination in Filtered Asset Search could have allowed a user to pass code through the provided search field. This issue affects version 6.6.80 and prior, and is fixed in 6.6.81. If your Security Console currently falls on or within this affected version range, ensure that you update your Security Console to the latest version.

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.
