CVE-2022-2237 1 Redhat 2 Keycloak Node.js Adapter, Single Sign-on 2023-12-10 N/A 6.1 MEDIUM
A flaw was found in the Keycloak Node.js Adapter. This flaw allows an attacker to benefit from an Open Redirect vulnerability in the checkSso function.
CVE-2023-1664 1 Redhat 5 Build Of Quarkus, Jboss A-mq, Keycloak and 2 more 2023-12-10 N/A 6.5 MEDIUM
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.
CVE-2022-4492 1 Redhat 10 Build Of Quarkus, Integration Camel For Spring Boot, Integration Camel K and 7 more 2023-12-10 N/A 7.5 HIGH
The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.
CVE-2023-0091 1 Redhat 2 Keycloak, Single Sign-on 2023-12-10 N/A 3.8 LOW
A flaw was found in Keycloak, where it did not properly check client tokens for possible revocation in its client credential flow. This flaw allows an attacker to access or modify potentially sensitive information.
CVE-2023-0105 1 Redhat 2 Keycloak, Single Sign-on 2023-12-10 N/A 6.5 MEDIUM
A flaw was found in Keycloak. This flaw allows impersonation and lockout due to the email trust not being handled correctly in Keycloak. An attacker can shadow other users with the same email and lockout or impersonate them.
CVE-2021-3632 1 Redhat 3 Enterprise Linux, Keycloak, Single Sign-on 2023-12-10 N/A 7.5 HIGH
A flaw was found in Keycloak. This vulnerability allows anyone to register a new security device or key when there is not a device already registered for any user by using the WebAuthn password-less login flow.
CVE-2021-3827 1 Redhat 4 Enterprise Linux, Keycloak, Openshift Container Platform and 1 more 2023-12-10 N/A 6.8 MEDIUM
A flaw was found in keycloak, where the default ECP binding flow allows other authentication flows to be bypassed. By exploiting this behavior, an attacker can bypass the MFA authentication by sending a SOAP request with an AuthnRequest and Authorization header with the user's credentials. The highest threat from this vulnerability is to confidentiality and integrity.
CVE-2022-2668 1 Redhat 2 Keycloak, Single Sign-on 2023-12-10 N/A 7.2 HIGH
An issue was discovered in Keycloak that allows arbitrary Javascript to be uploaded for the SAML protocol mapper even if the UPLOAD_SCRIPTS feature is disabled
CVE-2022-1278 1 Redhat 8 Amq, Amq Online, Integration Camel K and 5 more 2023-12-10 N/A 7.5 HIGH
A flaw was found in WildFly, where an attacker can see deployment names, endpoints, and any other data the trace payload may contain.
CVE-2022-1259 2 Netapp, Redhat 10 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 7 more 2023-12-10 N/A 7.5 HIGH
A flaw was found in Undertow. A potential security issue in flow control handling by the browser over HTTP/2 may cause overhead or a denial of service in the server. This flaw exists because of an incomplete fix for CVE-2021-3629.
CVE-2022-2764 2 Netapp, Redhat 9 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 6 more 2023-12-10 N/A 4.9 MEDIUM
A flaw was found in Undertow. Denial of service can be achieved as Undertow server waits for the LAST_CHUNK forever for EJB invocations.
CVE-2021-3690 1 Redhat 8 Enterprise Linux, Fuse, Integration Camel K and 5 more 2023-12-10 N/A 7.5 HIGH
A flaw was found in Undertow. A buffer leak on the incoming WebSocket PONG message may lead to memory exhaustion. This flaw allows an attacker to cause a denial of service. The highest threat from this vulnerability is availability.
CVE-2022-0225 1 Redhat 2 Keycloak, Single Sign-on 2023-12-10 N/A 5.4 MEDIUM
A flaw was found in Keycloak. This flaw allows a privileged attacker to use the malicious payload as the group name while creating a new group from the admin console, leading to a stored Cross-site scripting (XSS) attack.
CVE-2022-1319 2 Netapp, Redhat 7 Active Iq Unified Manager, Cloud Secure Agent, Oncommand Insight and 4 more 2023-12-10 N/A 7.5 HIGH
A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second SEND_HEADERS response packet instead of a CPONG.
CVE-2022-2256 1 Redhat 1 Single Sign-on 2023-12-10 N/A 3.8 LOW
A Stored Cross-site scripting (XSS) vulnerability was found in keycloak as shipped in Red Hat Single Sign-On 7. This flaw allows a privileged attacker to execute malicious scripts in the admin console, abusing the default roles functionality.
