CVE-2023-5685 1 Redhat 12 Apache-camel-spring-boot, Build Keycloak, Camel Spring Boot and 9 more 2024-11-26 7.5 High
A flaw was found in XNIO. The XNIO NotifierState that can cause a Stack Overflow Exception when the chain of notifier states becomes problematically large can lead to uncontrolled resource management and a possible denial of service (DoS).
CVE-2024-1300 1 Redhat 20 A Mq Clients, Amq Broker, Amq Streams and 17 more 2024-11-25 5.4 Medium
A vulnerability in the Eclipse Vert.x toolkit causes a memory leak in TCP servers configured with TLS and SNI support. When processing an unknown SNI server name assigned the default certificate instead of a mapped certificate, the SSL context is erroneously cached in the server name map, leading to memory exhaustion. This flaw allows attackers to send TLS client hello messages with fake server names, triggering a JVM out-of-memory error.
CVE-2024-1023 1 Redhat 20 A Mq Clients, Amq Broker, Amq Streams and 17 more 2024-11-25 6.5 Medium
A vulnerability in the Eclipse Vert.x toolkit results in a memory leak due to using Netty FastThreadLocal data structures. Specifically, when the Vert.x HTTP client establishes connections to different hosts, triggering the memory leak. The leak can be accelerated with intimate runtime knowledge, allowing an attacker to exploit this vulnerability. For instance, a server accepting arbitrary internet addresses could serve as an attack vector by connecting to these addresses, thereby accelerating the memory leak.
CVE-2024-3653 1 Redhat 17 Amq Streams, Build Keycloak, Camel Quarkus and 14 more 2024-11-25 5.3 Medium
A vulnerability was found in Undertow. This issue requires enabling the learning-push handler in the server's config, which is disabled by default, leaving the maxAge config in the handler unconfigured. The default is -1, which makes the handler vulnerable. If someone overwrites that config, the server is not subject to the attack. The attacker needs to be able to reach the server with a normal HTTP request.
CVE-2023-6544 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2024-11-25 5.4 Medium
A flaw was found in the Keycloak package. This issue occurs due to a permissive regular expression hardcoded for filtering which allows hosts to register a dynamic client. A malicious user with enough information about the environment could jeopardize an environment with this specific Dynamic Client Registration and TrustedDomain configuration previously unauthorized.
CVE-2024-7318 1 Redhat 2 Build Keycloak, Build Of Keycloak 2024-11-24 4.8 Medium
A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid.
CVE-2024-7260 1 Redhat 3 Build Keycloak, Build Of Keycloak, Keycloak 2024-11-24 6.1 Medium
An open redirect vulnerability was found in Keycloak. A specially crafted URL can be constructed where the referrer and referrer_uri parameters are made to trick a user to visit a malicious webpage. A trusted URL can trick users and automation into believing that the URL is safe, when, in fact, it redirects to a malicious server. This issue can result in a victim inadvertently trusting the destination of the redirect, potentially leading to a successful phishing attack or other types of attacks. Once a crafted URL is made, it can be sent to a Keycloak admin via email for example. This will trigger this vulnerability when the user visits the page and clicks the link. A malicious actor can use this to target users they know are Keycloak admins for further attacks. It may also be possible to bypass other domain-related security checks, such as supplying this as a OAuth redirect uri. The malicious actor can further obfuscate the redirect_uri using URL encoding, to hide the text of the actual malicious website domain.
CVE-2024-7341 1 Redhat 8 Build Keycloak, Build Of Keycloak, Enterprise Linux and 5 more 2024-11-24 7.1 High
A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
CVE-2024-5967 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2024-11-24 2.7 Low
A vulnerability was found in Keycloak. The LDAP testing endpoint allows changing the Connection URL  independently without re-entering the currently configured LDAP bind credentials. This flaw allows an attacker with admin access (permission manage-realm) to change the LDAP host URL ("Connection URL") to a machine they control. The Keycloak server will connect to the attacker's host and try to authenticate with the configured credentials, thus leaking them to the attacker. As a consequence, an attacker who has compromised the admin console or compromised a user with sufficient privileges can leak domain credentials and attack the domain.
CVE-2024-4629 1 Redhat 12 Build Keycloak, Build Of Keycloak, Enterprise Linux and 9 more 2024-11-24 6.5 Medium
A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.
CVE-2024-4029 1 Redhat 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more 2024-11-24 4.1 Medium
A vulnerability was found in Wildfly’s management interface. Due to the lack of limitation of sockets for the management interface, it may be possible to cause a denial of service hitting the nofile limit as there is no possibility to configure or set a maximum number of connections.
CVE-2024-2419 1 Redhat 1 Build Keycloak 2024-11-24 7.1 High
A flaw was found in Keycloak's redirect_uri validation logic. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to the theft of an access token, making it possible for the attacker to impersonate other users. It is very similar to CVE-2023-6291.
CVE-2024-1102 1 Redhat 6 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 3 more 2024-11-24 6.5 Medium
A vulnerability was found in jberet-core logging. An exception in 'dbProperties' might display user credentials such as the username and password for the database-connection.
CVE-2023-6927 1 Redhat 5 Build Keycloak, Keycloak, Red Hat Single Sign On and 2 more 2024-11-23 4.6 Medium
A flaw was found in Keycloak. This issue may allow an attacker to steal authorization codes or tokens from clients using a wildcard in the JARM response mode "form_post.jwt" which could be used to bypass the security patch implemented to address CVE-2023-6134.
CVE-2023-6563 1 Redhat 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more 2024-11-23 7.7 High
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2023-6134 1 Redhat 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more 2024-11-23 4.6 Medium
A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.
CVE-2023-3597 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2024-11-21 5 Medium
A flaw was found in Keycloak, where it does not correctly validate its client step-up authentication in org.keycloak.authentication. This flaw allows a remote user authenticated with a password to register a false second authentication factor along with an existing one and bypass authentication.
CVE-2024-10039 1 Redhat 1 Build Keycloak 2024-11-21 7.1 High
A vulnerability was found in Keycloak. Deployments of Keycloak with a reverse proxy not using pass-through termination of TLS, with mTLS enabled, are affected. This issue may allow an attacker on the local network to authenticate as any user or client that leverages mTLS as the authentication mechanism.
CVE-2024-5971 1 Redhat 12 Apache Camel Spring Boot, Build Keycloak, Camel Spring Boot and 9 more 2024-11-21 7.5 High
A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected 0\r\n termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios.
CVE-2024-4540 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2024-11-21 7.5 High
A flaw was found in Keycloak in OAuth 2.0 Pushed Authorization Requests (PAR). Client-provided parameters were found to be included in plain text in the KC_RESTART cookie returned by the authorization server's HTTP response to a `request_uri` authorization request, possibly leading to an information disclosure vulnerability.
