Detailsinfo

A vulnerability was found in Splunk Enterprise and Cloud Platform up to 8.x (Log Management Software). It has been classified as problematic. This affects an unknown code block of the file server.conf of the component Universal Forwarder. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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. See Configure universal forwarder management security (https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/EnableTLSCertHostnameValidation#Configure_universal_forwarder_management_security) for more information on disabling the remote management services.

The weakness was disclosed 06/15/2022. The advisory is shared at docs.splunk.com. This vulnerability is uniquely identified as CVE-2022-32155 since 05/31/2022. Technical details are known, but no exploit is available.
