CVSS 10.0 LXD, MicroCloud Flaw Lets Attackers Impersonate Trusted Clients Without a Private Key

By [email protected] (The Hacker News)

AI Summary

A CVSS 10.0 vulnerability in Canonical's LXD and MicroCloud allows an attacker to impersonate a trusted client without possessing the client's private key — requiring only network access to the HTTPS API and the target's public certificate. Successful exploitation grants full cluster access, including control over virtual machines, making this critical for any organization running LXD or MicroCloud in multi-tenant or cloud environments. Canonical patches should be applied immediately given the maximum severity rating and low attack complexity.

Relevance score: 88.0/100
