CVE-2017-2637

32
FAUCET Score

CVE-2017-2637 describes a critical design flaw in Red Hat OpenStack Platform director's use of TripleO for libvirtd-based live migration. The vulnerability arises because libvirtd is deployed by default listening on all interfaces (0.0.0.0) without authentication or encryption, affecting Red Hat OpenStack products. This allows any attacker with TCP connectivity to a compute host to establish a virsh session, potentially gaining control over virtual machines or even the host itself. With a CVSS score of 10.0 (CRITICAL), this vulnerability is easily exploitable over the network with no user interaction, leading to complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
