Description

In Kubernetes, if the logging level is set to at least 9, authorization and bearer tokens will be written to log files. This can occur both in API server logs and client tool output like kubectl. This affects <= v1.19.3, <= v1.18.10, <= v1.17.13, < v1.20.0-alpha2.

Solution(s)

  • kubernetes-upgrade-1_17_13
  • kubernetes-upgrade-1_18_10
  • kubernetes-upgrade-1_19_3

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
