CVE-2024-52506

Estado: AnalizadaAlta (7.1)—

Graylog is a free and open log management platform. The reporting functionality in Graylog allows the creation and scheduling of reports which contain dashboard widgets displaying individual log messages or metrics aggregated from fields of multiple log messages. This functionality, as included in Graylog 6.1.0 & 6.1.1, is vulnerable to information leakage triggered by multiple concurrent report rendering requests from authorized users. When multiple report renderings are requested at the same start time, the headless browser instance used to render the PDF will be reused.

Leer descripción completaMostrar menos

Depending on the timing, either a check for the browser instance "freshness" hits, resulting in an error instead of the report being returned, or one of the concurrent report rendering requests "wins" and this report is returned for all report rendering requests that do not return an error. This might lead to one user getting the report of a different user, potentially leaking indexed log messages or aggregated data that this user normally has no access to. This problem is fixed in Graylog 6.1.2. There is no known workaround besides disabling the reporting functionality.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso a red remota (AV:N, PR:L) a funcionalidad de reportes; reuso de instancia del navegador expone datos de otros usuarios sin autorización (CWE-200: información leakage).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

La función de generación de informes de Graylog permite la creación y programación de informes que contienen widgets de panel que muestran mensajes de registro individuales o métricas agregadas de campos de múltiples mensajes de registro. Esta función, incluida en Graylog 6.1.0 y 6.1.1, es vulnerable a la fuga de información provocada por múltiples solicitudes de generación de informes simultáneas de usuarios autorizados. Cuando se solicitan múltiples representaciones de informes al mismo tiempo de inicio, se reutilizará la instancia del navegador sin interfaz gráfica utilizada para generar el PDF. Según el momento, se realiza una comprobación de la \"actualidad\" de la instancia del navegador, lo que genera un error en lugar de devolver el informe, o bien una de las solicitudes de generación de informes simultáneas \"gana\" y este informe se devuelve para todas las solicitudes de generación de informes que no devuelven un error. Esto puede provocar que un usuario obtenga el informe de un usuario diferente, lo que podría filtrar mensajes de registro indexados o datos agregados a los que este usuario normalmente no tiene acceso. Este problema se solucionó en Graylog 6.1.2. No existe ningún workaround conocido, además de deshabilitar la función de generación de informes."
