Summary
A flaw was found in Keycloak. This flaw depends on a non-default configuration "Revalidate Client Certificate" to be enabled and the reverse proxy is not validating the certificate before Keycloak. Using this method an attacker may choose the certificate which will be validated by the server. If this happens and the KC_SPI_TRUSTSTORE_FILE_FILE variable is missing/misconfigured, any trustfile may be accepted with the logging information of "Cannot validate client certificate trust: Truststore not available". This may not impact availability as the attacker would have no access to the server, but consumer applications Integrity or Confidentiality may be impacted considering a possible access to them. Considering the environment is correctly set to use "Revalidate Client Certificate" this flaw is avoidable.

Summary
Keycloak Untrusted Certificate Validation vulnerability
Details
A flaw was found in keycloak-core. This flaw considers the scenario when using X509 Client Certificate Authenticatior with the option "Revalidate Client Certificate". A user may be able to choose, if directly connect to keycloak (not passing via reverse proxy) a specific certificate. If there's a configuration error in KC_SPI_TRUSTSTORE_FILE_FILE the authenticator allows even with the "Cannot validate client certificate trust: Truststore not available" message as there's no certificate to trust against.

Summary
Red Hat Security Advisory: Red Hat Single Sign-On 7.6.4 for OpenShift image security enhancement update
Notes
Topic
A new image is available for Red Hat Single Sign-On 7.6.4, running on OpenShift Container Platform 3.10 and 3.11, and 4.12.0.
Red Hat Product Security has rated this update as having a security impact of
Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat Single Sign-On is an integrated sign-on solution, available as a
Red Hat JBoss Middleware for OpenShift containerized image. The Red Hat
Single Sign-On for OpenShift image provides an authentication server that
you can use to log in centrally, log out, and register. You can also manage
user accounts for web applications, mobile applications, and RESTful web
services.
This erratum releases a new image for Red Hat Single Sign-On 7.6.4 for
use within the OpenShift Container Platform 3.10, OpenShift Container Platform
3.11, and within the OpenShift Container Platform 4.12 cloud computing Platform-as-a-Service (PaaS) for
on-premise or private cloud deployments, aligning with the standalone product release.
Security Fix(es):
* keycloak: Cross-site scripting when validating URI-schemes on SAML and OIDC (CVE-2022-4361)
* undertow: Infinite loop in SslConduit during close (CVE-2023-1108)
* keycloak: oauth client impersonation (CVE-2023-2422)
* keycloak: Untrusted Certificate Validation (CVE-2023-1664)
* keycloak: client access via device auth request spoof (CVE-2023-2585)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

gsd-2023-1664
Vulnerability from gsd
Modified
2023-12-13 01:20
Details
A flaw was found in Keycloak. This flaw depends on a non-default configuration "Revalidate Client Certificate" to be enabled and the reverse proxy is not validating the certificate before Keycloak. Using this method an attacker may choose the certificate which will be validated by the server. If this happens and the KC_SPI_TRUSTSTORE_FILE_FILE variable is missing/misconfigured, any trustfile may be accepted with the logging information of "Cannot validate client certificate trust: Truststore not available". This may not impact availability as the attacker would have no access to the server, but consumer applications Integrity or Confidentiality may be impacted considering a possible access to them. Considering the environment is correctly set to use "Revalidate Client Certificate" this flaw is avoidable.
