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

The Hacker News

A serious vulnerability has been discovered in Canonical's LXD and MicroCloud, allowing attackers to log in as a trusted client without needing the client's private key. To exploit this flaw, an attacker only requires access to the trusted client's public certificate and the ability to reach the HTTPS API over the network. Once authenticated, the attacker can impersonate the client, gaining access to the entire cluster and its virtual machines. This breach poses significant risks, especially if the impersonated account has elevated privileges, potentially leading to unauthorized data access or manipulation. Users of LXD and MicroCloud should take immediate action to secure their systems against this vulnerability.
