SCA: security update for org.graylog2:graylog2-server (GHSA-3fqm-frhg-7c85)
low Tenable Cloud Security Plugin ID 409495
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Graylog is a free and open log management platform. In a multi-node Graylog cluster, after a user has
explicitly logged out, a user session may still be used for API requests until it has reached its original
expiry time. Each node maintains an in-memory cache of user sessions. Upon a cache-miss, the session is
loaded from the database. After that, the node operates solely on the cached session. Modifications to
sessions will update the cached version as well as the session persisted in the database. However, each
node maintains their isolated version of the session. When the user logs out, the session is removed from
the node-local cache and deleted from the database. The other nodes will however still use the cached
session. These nodes will only fail to accept the session id if they intent to update the session in the
database. They will then notice that the session is gone. This is true for most API requests originating
from user interaction with the Graylog UI because these will lead to an update of the session's "last
access" timestamp. If the session update is however prevented by setting the `X-Graylog-No-Session-
Extension:true` header in the request, the node will consider the (cached) session valid until the session
is expired according to its timeout setting. No session identifiers are leaked. After a user has logged
out, the UI shows the login screen again, which gives the user the impression that their session is not
valid anymore. However, if the session becomes compromised later, it can still be used to perform API
requests against the Graylog cluster. The time frame for this is limited to the configured session
lifetime, starting from the time when the user logged out. This issue has been addressed in versions 5.0.9
and 5.1.3. Users are advised to upgrade. (CVE-2023-41041)
