Arch Linux Security Advisory ASA-202106-53
Date : 2021-06-22
CVE-ID : CVE-2020-35509
Package : keycloak
Type : certificate verification bypass
Remote : Yes
Link : https://security.archlinux.org/AVG-2084
The package keycloak before version 14.0.0-1 is vulnerable to
certificate verification bypass.
Upgrade to 14.0.0-1.
# pacman -Syu "keycloak>=14.0.0-1"
The problem has been fixed upstream in version 14.0.0.
A security issue has been found in Keycloak before version 14.0.0.
Depending on the webserver configuration, a malicious user can supply
an expired certificate and it would be accepted by Keycloak direct-
grant authenticator. This is because Keycloak does not trigger the
appropriate timestamp validation.
A user could authenticate with an expired certificate.
