Session ID leak in Graylog DEBUG log file and audit log.

We recently discovered a session ID leak in the Graylog DEBUG log file as well as the audit log. A user can use a session ID to authenticate against Graylog and then this user has access to all the permissions associated with the owner of the session ID.

The ID was printed in DEBUG level log messages (DEBUG is not enabled by default) as well as the Graylog Enterprise Audit Log. By default, the Graylog Audit Log is only logging to the local database and only accessible by Graylog administrators.

We would like to thank David Herbstmann for discovering and responsibly disclosing this vulnerability.

  • Fixing a path traversal issue in the API Browser for non-standard installations. Graylog2/graylog2-server#8986Graylog2/graylog2-server#8988 Due to a check happening before pathname normalization, a directory traversal was possible in the REST resource that serves the API browser UI. If the Graylog server was started with non-standard JRE options (using an additional classpath setting), it could have been used to access files from this additional classpath directory without authentication. Many thanks to Florian Hauser and Christian Fünfhaus of Code White for disclosing this vulnerability.

  • [BREAKING]: Enable hostname validation for SSL/TLS-backed LDAP connections. Graylog2/graylog2-server#8625 Prior to v3.3.3, the certificates of LDAP servers which are connected to using a secure connection (SSL or TLS) were not validated, even if the “Allow self-signed certificates” option was unchecked. Starting with v3.3.3, certificates are validated against the local default keystore. This might introduce a breaking change, depending on your local LDAP settings and the validity of the certificates used (if any). Please ensure that all certificates used are valid, their common name matches the host part of your configured LDAP server and your local keystore contains all CA/intermediate certs required for validation.
