CVE-2023-29002  (opens in a new tab)
CWE-532  (opens in a new tab)

How to fix?

Upgrade github.com/cilium/cilium/pkg/envoy to version 1.11.16, 1.12.9, 1.13.2 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure such that when run in debug mode, Cilium will log the contents of the cilium-secrets namespace. This could include data such as TLS private keys for Ingress and GatewayAPI resources. An attacker with access to debug output from the Cilium containers could use the resulting output to intercept and modify traffic to and from the affected cluster. Output of the sensitive information would occur at Cilium agent restart, when secrets in the namespace are modified, and on creation of Ingress or GatewayAPI resources.

Workaround

Users unable to upgrade should disable debug mode.
