Technical Description
Graylog is a free and open log management platform. Starting with 6.1, HTTP Inputs can be configured to check if a specified header is present and has a specified value to authenticate HTTP-based ingestion. Unfortunately, even though in cases of a missing header or a wrong value the correct HTTP response (401) is returned, the message will be ingested nonetheless. To mitigate the vulnerability, disable http-based inputs and allow only authenticated pull-based inputs. This vulnerability is fixed in 6.1.9.
Remediation
Check the references section for vendor advisories and patches from graylog. Update graylog to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
