14 Jun 2024 — A flaw was found in Undertow, which incorrectly parses cookies with certain value-delimiting characters in incoming requests. This issue could allow an attacker to construct a cookie value to exfiltrate HttpOnly cookie values or spoof arbitrary additional cookie values, leading to unauthorized data access or modification. The main threat from this flaw impacts data confidentiality and integrity. • https://access.redhat.com/errata/RHSA-2024:1674 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

25 Apr 2024 — A flaw was found in the SAML client registration in Keycloak that could allow an administrator to register malicious JavaScript URIs as Assertion Consumer Service POST Binding URLs (ACS), posing a Cross-Site Scripting (XSS) risk. This issue may allow a malicious admin in one realm or a client with registration access to target users in different realms or applications, executing arbitrary JavaScript in their contexts upon form submission. This can enable unauthorized access and harmful actions, compromising... • https://access.redhat.com/errata/RHSA-2024:1867 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

17 Apr 2024 — A flaw was found in Keycloak's OIDC component in the "checkLoginIframe," which allows unvalidated cross-origin messages. This flaw allows attackers to coordinate and send millions of requests in seconds using simple code, significantly impacting the application's availability without proper origin validation for incoming messages. Se encontró una falla en el componente OIDC de Keycloak en "checkLoginIframe", que permite mensajes de origen cruzado no validados. Esta falla permite a los atacantes coordinar y ... • https://access.redhat.com/errata/RHSA-2024:1860 • CWE-346: Origin Validation Error •

17 Apr 2024 — A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL.

02 Apr 2024 — 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. Una vulnerabilidad en Eclipse Vert.x toolkit provoca una pérdida de m... • https://access.redhat.com/errata/RHSA-2024:1662 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •

27 Mar 2024 — 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 le... • https://access.redhat.com/errata/RHSA-2024:1662 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-401: Missing Release of Memory after Effective Lifetime •

26 Jan 2024 — 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. Se encontró un fallo en la lógica de validación de redirect_uri en Keycloak. Este problema puede permitir la omisión de hosts permitidos explícitamente. • https://access.redhat.com/errata/RHSA-2023:7854 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

10 Oct 2023 — The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023.

23 Feb 2023 — 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. A flaw was found in undertow. The undertow client is not checking the server identity the server certificate presents in HTTPS connections. • https://access.redhat.com/security/cve/CVE-2022-4492 • CWE-550: Server-generated Error Message Containing Sensitive Information •
