Man-in-the-middle via unvalidated SSL certificates
Published Feb 27, 2021 · Updated Oct 15, 2024
Improper SSL certificate validation in SaltStack Salt before 3002.5 allows man-in-the-middle attackers to read or alter authenticated service traffic. Several Salt runners, returners, proxies, and service-authentication modules failed to validate the remote server certificate by default, allowing an intercepted connection to accept an impostor endpoint. Exploitation requires network interception of a service connection made by an affected module; the documented consequence is disclosure or modification of sensitive traffic.
