## Overview

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.

## Affected

- `docker_images >= 8.0.0 <= 8.19.23`
- `docker_images >= 9.0.0 <= 9.4.8`
- `docker_images >= 9.5.0 <= 9.5.5`
