GSD-2019-7615

Vulnerability from gsd - Updated: 2022-05-24 00:00
Details
A TLS certificate validation flaw was found in Elastic APM agent for Ruby versions before 2.9.0. When specifying a trusted server CA certificate via the `server_ca_cert` setting, the Ruby agent would not properly verify the certificate returned by the APM server. This could result in a man in the middle style attack against the Ruby agent.
