| 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-2023-6291 | 1 Redhat | 18 Build Keycloak, Enterprise Linux, Jboss Data Grid and 15 more | 2024-11-23 | 7.1 High |
| A flaw was found in the redirect_uri validation logic in Keycloak. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to an access token being stolen, making it possible for the attacker to impersonate other users. | ||||
| 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-2024-4629 | 1 Redhat | 12 Build Keycloak, Build Of Keycloak, Enterprise Linux and 9 more | 2024-11-21 | 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-2023-4918 | 1 Redhat | 2 Keycloak, Red Hat Single Sign On | 2024-11-21 | 8.8 High |
| A flaw was found in the Keycloak package, more specifically org.keycloak.userprofile. When a user registers itself through registration flow, the "password" and "password-confirm" field from the form will occur as regular user attributes. All users and clients with proper rights and roles are able to read users attributes, allowing a malicious user with minimal access to retrieve the users passwords in clear text, jeopardizing their environment. | ||||
| CVE-2023-48795 | 43 9bis, Apache, Apple and 40 more | 78 Kitty, Sshd, Sshj and 75 more | 2024-11-21 | 5.9 Medium |
| The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust. | ||||
| CVE-2023-2422 | 1 Redhat | 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more | 2024-11-21 | 5.5 Medium |
| A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients. | ||||
| CVE-2023-1664 | 1 Redhat | 8 Amq Broker, Build Of Quarkus, Jboss A-mq and 5 more | 2024-11-21 | 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-2023-0264 | 1 Redhat | 8 Enterprise Linux, Keycloak, Openshift Container Platform and 5 more | 2024-11-21 | 5.0 Medium |
| A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate requests. An authenticated attacker who could obtain information from a user request within the same realm could use that data to impersonate the victim and generate new session tokens. This issue could impact confidentiality, integrity, and availability. | ||||
| CVE-2023-0105 | 1 Redhat | 4 Keycloak, Red Hat Single Sign On, Rhosemc and 1 more | 2024-11-21 | 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-2023-0091 | 1 Redhat | 4 Keycloak, Red Hat Single Sign On, Rhosemc and 1 more | 2024-11-21 | 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-2022-4361 | 1 Redhat | 8 Enterprise Linux, Keycloak, Openshift Container Platform and 5 more | 2024-11-21 | 10 Critical |
| Keycloak, an open-source identity and access management solution, has a cross-site scripting (XSS) vulnerability in the SAML or OIDC providers. The vulnerability can allow an attacker to execute malicious scripts by setting the AssertionConsumerServiceURL value or the redirect_uri. | ||||
| CVE-2022-4137 | 1 Redhat | 4 Enterprise Linux, Keycloak, Red Hat Single Sign On and 1 more | 2024-11-21 | 8.1 High |
| A reflected cross-site scripting (XSS) vulnerability was found in the 'oob' OAuth endpoint due to incorrect null-byte handling. This issue allows a malicious link to insert an arbitrary URI into a Keycloak error page. This flaw requires a user or administrator to interact with a link in order to be vulnerable. This may compromise user details, allowing it to be changed or collected by an attacker. | ||||
| CVE-2022-3916 | 1 Redhat | 9 Enterprise Linux, Keycloak, Openshift Container Platform and 6 more | 2024-11-21 | 6.8 Medium |
| A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user. | ||||
| CVE-2022-3782 | 1 Redhat | 8 Amq Broker, Jboss Enterprise Bpms Platform, Keycloak and 5 more | 2024-11-21 | 9.1 Critical |
| keycloak: path traversal via double URL encoding. A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. An attacker can use this flaw to construct a malicious request to bypass validation and access other URLs and potentially sensitive information within the domain or possibly conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field. | ||||
| CVE-2022-2668 | 1 Redhat | 3 Keycloak, Red Hat Single Sign On, Single Sign-on | 2024-11-21 | 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-2022-1466 | 1 Redhat | 3 Keycloak, Red Hat Single Sign On, Single Sign-on | 2024-11-21 | 6.5 Medium |
| Due to improper authorization, Red Hat Single Sign-On is vulnerable to users performing actions that they should not be allowed to perform. It was possible to add users to the master realm even though no respective permission was granted. | ||||
| CVE-2022-1438 | 1 Redhat | 3 Keycloak, Red Hat Single Sign On, Rhosemc | 2024-11-21 | 6.4 Medium |
| A flaw was found in Keycloak. Under specific circumstances, HTML entities are not sanitized during user impersonation, resulting in a Cross-site scripting (XSS) vulnerability. | ||||
| CVE-2022-1274 | 1 Redhat | 10 Enterprise Linux, Enterprise Linux For Ibm Z Systems, Enterprise Linux For Ibm Z Systems Eus and 7 more | 2024-11-21 | 5.4 Medium |
