CVE Published:

Summary

A security flaw exists in the Elastic APM agent for Ruby, specifically in its ability to validate TLS certificates. When configuring a trusted server CA certificate using the 'server_ca_cert' setting, the Ruby agent fails to appropriately verify the certificate provided by the APM server. This oversight may leave the application vulnerable to man-in-the-middle attacks, enabling unauthorized access to communications between the Ruby agent and the server, which could compromise sensitive data.

Affected Version(s)

Elastic APM agent for Ruby before 2.9.0
