Official description

Improper authentication for some Intel Unison software may allow an authenticated user to potentially enable escalation of privilege via network access.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
