CVE-2026-76402
Beschrijving NL
In Splunk Connect voor Kafka-versies hieronder 2.2.7 kan een niet-geverifieerde gebruiker die de Kafka Connect Representational State Transfer (REST) API kan bereiken, een niet-beveiligd Hypertext Transfer Protocol (HTTP) Event Collector-eindpunt in Splunk Enterprise configureren dat ervoor zorgt dat de connector authenticatiegegevens naar een door aanvallers gecontroleerde server verzendt, waardoor inloggegevens kunnen worden weergegeven die alle relevante gegevens die via de connector zijn verzonden, in gevaar brengen en de wijziging van ev ent levering. De kwetsbaarheid is mogelijk omdat HTTP Event Collector-eindpuntvalidatie standaard geen beveiligd transport vereist. Zie voor meer informatie Splunk Connect installeren voor Kafka (https://help.splunk.com/en/data-management/integrate-data-with-add-ons/splunk-connect-for-kafka/2 .2/install/install-splunk-connect-for-kafka), Gegevensopnameparameters voor Splunk Connect voor Kafka (https://help.splunk.com/en/data-management/integrate-data-with-add-ons/splunk-connect-for-kafka/2 .2/overview/data-ingestion-parameters-for-splunk-connect-for-kafka) en HTTP Event Collector instellen en gebruiken met configurati op bestanden (https://help.splunk.com/en/splunk-enterprise/get-data-in/get-started-with-getting-data-in/9.4/get-data-with-http-event-collector/set-up-and-use-http-event-collector-with-configuration-files) in de Splunk documentatie.
Origineel (Engels) tonen
In Splunk Connect for Kafka versions below 2.2.7, an unauthenticated user who can reach the Kafka Connect Representational State Transfer (REST) API could configure a non-secure Hypertext Transfer Protocol (HTTP) Event Collector endpoint in Splunk Enterprise that causes the connector to send authentication credentials to an attacker-controlled server, allowing for exposure of credentials that compromise all relevant data sent through the connector and limited alteration of event delivery. The vulnerability is possible because HTTP Event Collector endpoint validation does not require secure transport by default.
