Description

Improper authentication in Azure Local Disconnected Operations allows an unauthorized attacker to elevate privileges over a network.

Source: NVD

QSearch commentary

Cloud control planes are the next compliance battleground. Azure Local Disconnected Operations exposing a privilege-elevation pathway over the network — without authentication — is the kind of identity-boundary defect that DORA and NIS2 audits will catch this year. Cloud Security engagements at QSearch test exactly this class of cross-tenant and cross-boundary privilege escalations.
