Branch: refs/heads/master Home: https://github.com/tribe29/checkmk Commit: 960c4f3680140964c41cdc0a889d4184eebb00f7 https://github.com/tribe29/checkmk/commit/960c4f3680140964c41cdc0a889d4184e… Author: Lars Michelsen <lm(a)tribe29.com> Date: 2020-09-16 (Wed, 16 Sep 2020) Changed paths: A .werks/11492 Log Message: ----------- 11491 SEC Auth cookies: Specify SameSite attribute to improve cookie security The authentication cookies of the Checkmk GUI (auth_[site]) previously relied on the browsers default behaviour regarding the same site policy. This resulted in a) an inconsistent cookie handling across the different browsers and b) allow some sort of Cross-site request forgery (CSRF) attacks. With this change we explicitly set the "SameSite=Lax" setting for all authentication cookies created by logins after updating Checkmk. For more information about this HTTP cookie setting have a look at https://web.dev/samesite-cookies-explained/. Change-Id: I42fd2d654f8364b6b90233f5aac9c71180b903d9
