CVE-2022-27225Network attack vector

Session hijacking via insecure legacy cookies

Published Mar 16, 2022 · Updated Aug 3, 2024

Cleartext cookie transmission in Gradle Enterprise 2020.1 through 2021.4.2 enables attackers to capture authenticated sessions. Keycloak sets duplicate legacy cookies ending in _LEGACY without the Secure attribute; browsers transmit the cookies over plain HTTP. Exploitation requires host impersonation and an authenticated victim clicking an HTTP link, resulting in capture of the victim's login session.
