Kibana 9.0.x < 9.4.9 / 9.5.x < 9.5.6 (ESA-2026-229)

medium Nessus Plugin ID 375654

Synopsis

The remote host is affected by a vulnerability.

Description

The version of Kibana installed on the remote host is 9.0.x prior to 9.4.9, or 9.5.x prior to 9.5.6. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-229 advisory.

- The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed. (CVE-2026-114406)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Kibana version 9.4.9, or 9.5.6 or later as appropriate for your release branch.
