Description

kube-audit-rest's example logging configuration could disclose secret values in the audit log

Impact

What kind of vulnerability is it? Who is impacted? If the "full-elastic-stack" example vector configuration was used for a real cluster, the previous values of kubernetes secrets would have been disclosed in the audit messages.

Patches

Has the problem been patched? What versions should users upgrade to? The example has been updated to fix this in commit 9df8886b4819409f566233adc7c3b7a43a4096ba

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading? Replace

          if .request.requestKind.kind == "Secret" {
            del(.request.object.data)
            .request.object.data.redacted = "REDACTED"
            del(.request.oldObject.data)
            .request.oldObject.data.redacted = "REDACTED"
          }

In the vector "audit-files-json-parser-and-redaction" step with

          if .request.requestKind.kind == "Secret" {
            # Redact the secret data
            del(.request.object.data)
            .request.object.data.redacted = "REDACTED"
            del(.request.oldObject.data)
            .request.oldObject.data.redacted = "REDACTED"
            # Remove the previously set secret data - Not bothering to parse it as this annotation shouldn't ever be needed...
