Title

Org.keycloak/keycloak-services: open redirect when using wildcard valid redirect uris in keycloak

Summary

A flaw was found in Keycloak's URL validation logic during redirect operations. By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the "Valid Redirect URIs" field and requires user interaction to be successfully exploited. The issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java's URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak's validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect.

Changes to client configurations in Keycloak may require a restart or reload of the Keycloak service to take effect, which could impact active user sessions."

By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the \"Valid Redirect URIs\" field and requires user interaction to be successfully exploited.\n\nThe issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java\u0027s URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak\u0027s validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect."

By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the \"Valid Redirect URIs\" field and requires user interaction to be successfully exploited.\n\nThe issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java\u0027s URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak\u0027s validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect."

Esta vulnerabilidad afecta espec\u00edficamente a clientes de Keycloak configurados con un comod\u00edn (*) en el campo \u2019Valid Redirect URIs\u2019 y requiere interacci\u00f3n del usuario para ser explotada con \u00e9xito.\n\nEl problema se deriva de una discrepancia en c\u00f3mo Keycloak y la implementaci\u00f3n subyacente de URI de Java manejan el componente de informaci\u00f3n de usuario (user-info) de una URL. Si se construye una URL de redirecci\u00f3n maliciosa utilizando m\u00faltiples caracteres @ en la secci\u00f3n de informaci\u00f3n de usuario (user-info), el analizador de URI de Java no logra extraer la informaci\u00f3n de usuario (user-info), dejando solo el campo de autoridad sin procesar. En consecuencia, la verificaci\u00f3n de validaci\u00f3n de Keycloak no logra detectar la informaci\u00f3n de usuario (user-info) malformada, recurre a una comparaci\u00f3n con comod\u00edn y permite incorrectamente la redirecci\u00f3n maliciosa."

By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the \"Valid Redirect URIs\" field and requires user interaction to be successfully exploited.\n\nThe issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java\u0027s URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak\u0027s validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect."

By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the \"Valid Redirect URIs\" field and requires user interaction to be successfully exploited.\n\nThe issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java\u0027s URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak\u0027s validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect."

Summary

Org.keycloak/keycloak-services: open redirect when using wildcard valid redirect uris in keycloak

Details

The issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java's URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak's validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect.

By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the \"Valid Redirect URIs\" field and requires user interaction to be successfully exploited.\n\nThe issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java\u0027s URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak\u0027s validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect."

Esta vulnerabilidad afecta espec\u00edficamente a clientes de Keycloak configurados con un comod\u00edn (*) en el campo \u2019Valid Redirect URIs\u2019 y requiere interacci\u00f3n del usuario para ser explotada con \u00e9xito.\n\nEl problema se deriva de una discrepancia en c\u00f3mo Keycloak y la implementaci\u00f3n subyacente de URI de Java manejan el componente de informaci\u00f3n de usuario (user-info) de una URL. Si se construye una URL de redirecci\u00f3n maliciosa utilizando m\u00faltiples caracteres @ en la secci\u00f3n de informaci\u00f3n de usuario (user-info), el analizador de URI de Java no logra extraer la informaci\u00f3n de usuario (user-info), dejando solo el campo de autoridad sin procesar. En consecuencia, la verificaci\u00f3n de validaci\u00f3n de Keycloak no logra detectar la informaci\u00f3n de usuario (user-info) malformada, recurre a una comparaci\u00f3n con comod\u00edn y permite incorrectamente la redirecci\u00f3n maliciosa."

  "details": "A flaw was found in Keycloak\u0027s URL validation logic during redirect operations. By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further attacks. This vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the \"Valid Redirect URIs\" field and requires user interaction to be successfully exploited.\n\nThe issue stems from a discrepancy in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a malicious redirect URL is constructed using multiple @ characters in the user-info section, Java\u0027s URI parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak\u0027s validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and incorrectly permits the malicious redirect.",
