CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-37439 – Malformed ZIP file crashes Universal Forwarders and Splunk Enterprise through file monitoring input
https://notcve.org/view.php?id=CVE-2022-37439
In Splunk Enterprise and Universal Forwarder versions in the following table, indexing a specially crafted ZIP file using the file monitoring input can result in a crash of the application. Attempts to restart the application would result in a crash and would require manually removing the malformed file. En las versiones de Splunk Enterprise y Universal Forwarder de la siguiente tabla, la indexación de un archivo ZIP especialmente diseñado mediante la entrada de monitorización de archivos puede resultar en un bloqueo de la aplicación. Los intentos de reiniciar la aplicación resultarían en un bloqueo y requerirían la eliminación manual del archivo malformado. • https://research.splunk.com/application/b237d393-2f57-4531-aad7-ad3c17c8b041 https://www.splunk.com/en_us/product-security/announcements/svd-2022-0803.html • CWE-409: Improper Handling of Highly Compressed Data (Data Amplification) •
CVSS: 3.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-37438 – Information disclosure via the dashboard drilldown in Splunk Enterprise
https://notcve.org/view.php?id=CVE-2022-37438
In Splunk Enterprise versions in the following table, an authenticated user can craft a dashboard that could potentially leak information (for example, username, email, and real name) about Splunk users, when visited by another user through the drilldown component. The vulnerability requires user access to create and share dashboards using Splunk Web. En las versiones de Splunk Enterprise de la siguiente tabla, un usuario autenticado puede diseñar un panel de control que podría filtrar información (por ejemplo, nombre de usuario, correo electrónico y nombre real) sobre los usuarios de Splunk, cuando es visitado por otro usuario por medio del componente drilldown. La vulnerabilidad requiere el acceso del usuario para crear y compartir cuadros de mando usando Splunk Web. • https://research.splunk.com/application/f844c3f6-fd99-43a2-ba24-93e35fe84be6 https://www.splunk.com/en_us/product-security/announcements/svd-2022-0802.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 10.0EPSS: 0%CPEs: 1EXPL: 0CVE-2022-32158 – Splunk Enterprise deployment servers allow client publishing of forwarder bundles
https://notcve.org/view.php?id=CVE-2022-32158
Splunk Enterprise deployment servers in versions before 8.1.10.1, 8.2.6.1, and 9.0 let clients deploy forwarder bundles to other deployment clients through the deployment server. An attacker that compromised a Universal Forwarder endpoint could use the vulnerability to execute arbitrary code on all other Universal Forwarder endpoints subscribed to the deployment server. Los servidores de despliegue de Splunk Enterprise en versiones anteriores a la 8.1.10.1, 8.2.6.1 y 9.0 permiten a los clientes desplegar paquetes de reenvío a otros clientes de despliegue a través del servidor de despliegue. Un atacante que comprometiera un punto final de Universal Forwarder podría utilizar la vulnerabilidad para ejecutar código arbitrario en todos los demás puntos finales de Universal Forwarder suscritos al servidor de despliegue • https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/Updates https://www.splunk.com/en_us/product-security/announcements/svd-2022-0608.html • CWE-284: Improper Access Control •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2022-32157 – Splunk Enterprise deployment servers allow unauthenticated forwarder bundle downloads
https://notcve.org/view.php?id=CVE-2022-32157
Splunk Enterprise deployment servers in versions before 9.0 allow unauthenticated downloading of forwarder bundles. Remediation requires you to update the deployment server to version 9.0 and Configure authentication for deployment servers and clients (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/ConfigDSDCAuthEnhancements#Configure_authentication_for_deployment_servers_and_clients). Once enabled, deployment servers can manage only Universal Forwarder versions 9.0 and higher. Though the vulnerability does not directly affect Universal Forwarders, remediation requires updating all Universal Forwarders that the deployment server manages to version 9.0 or higher prior to enabling the remediation. Los servidores de implementación de Splunk Enterprise en versiones anteriores a 9.0, permiten una descarga no autenticada de paquetes de reenvío. • https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/ConfigDSDCAuthEnhancements#Configure_authentication_for_deployment_servers_and_clients https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/Updates https://research.splunk.com/application/splunk_process_injection_forwarder_bundle_downloads https://www.splunk.com/en_us/product-security/announcements/svd-2022-0607.html • CWE-306: Missing Authentication for Critical Function •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-32155 – Universal Forwarder management services allows remote login by default
https://notcve.org/view.php?id=CVE-2022-32155
In universal forwarder versions before 9.0, management services are available remotely by default. When not required, it introduces a potential exposure, but it is not a vulnerability. If exposed, we recommend each customer assess the potential severity specific to your environment. In 9.0, the universal forwarder now binds the management port to localhost preventing remote logins by default. If management services are not required in versions before 9.0, set disableDefaultPort = true in server.conf OR allowRemoteLogin = never in server.conf OR mgmtHostPort = localhost in web.conf. • https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/EnableTLSCertHostnameValidation#Configure_universal_forwarder_management_security https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/Updates https://www.splunk.com/en_us/product-security/announcements/svd-2022-0605.html • CWE-732: Incorrect Permission Assignment for Critical Resource •
