CVE-2014-0161Network attack vector

Endpoint spoofing via missing TLS hostname verification

Published Jan 2, 2020 · Updated Aug 6, 2024

Improper certificate validation in oVirt Engine API Python SDK before 3.4.0.7 and 3.5.0.4 allows man-in-the-middle attackers to spoof endpoints. The SDK's TLS client accepts an arbitrary valid X.509 certificate without comparing the requested hostname with its Common Name or subjectAltName. An attacker must intercept the SDK-to-Engine connection and present that certificate, permitting trusted API traffic to be redirected or modified.
