CVE-2022-32290

mTLS authentication bypass via exposed HTTP proxy

Published Jul 6, 2022 · Updated Aug 3, 2024

Incorrect access control in Northern.tech Mender Client 3.2.0 through 3.2.2 allows remote attackers on the same network to proxy HTTP requests. The client's random unprivileged TCP listener binds to every network interface rather than localhost and forwards received requests to Mender Server. When mTLS is configured, forwarded requests use the device certificate, bypassing server authentication without exposing its private key; the proxy alone discloses no device or server data.
