CVE-2025-53106

Estado: AnalizadaAlta (8.8)—

Graylog is a free and open log management platform. In versions 6.2.0 to before 6.2.4 and 6.3.0-alpha.1 to before 6.3.0-rc.2, Graylog users can gain elevated privileges by creating and using API tokens for the local Administrator or any other user for whom the malicious user knows the ID. For the attack to succeed, the attacker needs a user account in Graylog. They can then proceed to issue hand-crafted requests to the Graylog REST API and exploit a weak permission check for token creation. This issue has been patched in versions 6.2.4 and 6.3.0-rc.2. A workaround involves disabling the respective configuration found in System > Configuration > Users > "Allow users to create personal access tokens".

En las versiones 6.2.0 y anteriores a la 6.2.4 y 6.3.0-alpha.1 y anteriores a la 6.3.0-rc.2, los usuarios de Graylog pueden obtener privilegios elevados mediante la creación y el uso de tokens de API para el administrador local o cualquier otro usuario cuyo ID conozca el usuario malicioso. Para que el ataque tenga éxito, el atacante necesita una cuenta de usuario en Graylog. Posteriormente, puede emitir solicitudes personalizadas a la API REST de Graylog y aprovechar una verificación de permisos deficiente para la creación de tokens. Este problema se ha corregido en las versiones 6.2.4 y 6.3.0-rc.2. Una solución alternativa consiste en deshabilitar la configuración correspondiente en Sistema &gt; Configuración &gt; Usuarios &gt; \"Permitir a los usuarios crear tokens de acceso personales\"."
