Vulnerability Information

Elasticsearch Insertion of sensitive information in audit logs (ESA-2023-12)

Elasticsearch generally filters out sensitive information and credentials before logging to the audit log. It was found that this filtering was not applied when requests to Elasticsearch use certain deprecated URIs for APIs. The impact of this flaw is that sensitive information such as passwords and tokens might be printed in cleartext in Elasticsearch audit logs. Note that audit logging is disabled by default and needs to be explicitly enabled and even when audit logging is enabled, request bodies that could contain sensitive information are not printed to the audit log unless explicitly configured.

The _xpack/security APIs have been deprecated in Elasticsearch 7.x and were entirely removed in 8.0.0 and later. The only way for a client to use them in Elasticsearch 8.0.0 and later is to provide the Accept: application/json; compatible-with=7 header. Elasticsearch official clients do not use these deprecated APIs.

The list of affected, deprecated APIs, is the following

• POST /_xpack/security/user/{username}
• PUT /_xpack/security/user/{username}
• PUT /_xpack/security/user/{username}/_password
• POST /_xpack/security/user/{username}/_password
• PUT /_xpack/security/user/_password
• POST /_xpack/security/user/_password
• POST /_xpack/security/oauth2/token
• DELETE /_xpack/security/oauth2/token
• POST /_xpack/security/saml/authenticate

Affected Versions:

Elasticsearch versions from 7.0.0 up to 7.17.12 and from 8.0.0 up to 8.9.1

Solutions and Mitigations:

The issue is resolved in version 7.17.13 and 8.9.2

CVSSv3.1: 4.1(Medium) AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N
CVE ID: CVE-2023-31417

Additional Information

Liferay DXP's out-of-the-box integration with Elasticsearch's X-Pack security features to provide encrypted and authenticated connection between the search engine and Liferay nodes are not using _xpack/security APIs to manage users or OAuth2 tokens.
