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
A persistent cross-site scripting vulnerability in the UI framework used by Junos Space Security Director may allow authenticated users to inject persistent and malicious scripts. This may allow stealing of information or performing actions as a different user when other users access the Security Director web interface. This issue affects all versions of Juniper Networks Junos Space Security Director prior to 17.2R2.

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.
