Until a fix is available, users should consider mitigating risk by restricting network access to trusted parties and monitoring for suspicious TLS certificates. Follow Elastic's official advisories for updates and apply patches promptly once released.

Description

Improper Certificate Validation (CWE-295) in the operating system certificate bundle shipped in the Docker images of APM Server; Auditbeat, Filebeat, Heartbeat, Metricbeat and Packetbeat; Elastic Agent, including Fleet Server and Cloudbeat; Logstash, for TLS connections that use the operating system certificate bundle; Elastic connectors; Universal Profiling (host agent, collector and symbolizer); and Elastic Maps Server. This certificate bundle, a dependency of these products (Dependency on Vulnerable Third-Party Component, CWE-1395), could allow an attacker to intercept or modify TLS-protected traffic via Signature Spoofing by Key Theft (CAPEC-474). The certificate bundle includes root certificate authorities that signed eight eMudhra intermediate certificate authorities whose private keys are compromised. Anyone with these keys can issue a certificate for any host name that these products accept as trusted. Exploitation requires an attacker in a network position between the product and the remote party, who presents a certificate issued with one of the compromised keys.
