Elastic APM agent for Ruby vulnerable to Improper Certificate Validation
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| RubyGems | elastic-apm | < 2.9.0 | 2.9.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
