Detailsinfo

A vulnerability has been found in Cilium up to 1.11.15/1.12.8/1.13.1 and classified as problematic. This vulnerability affects an unknown function of the component Debug Mode. The manipulation with an unknown input leads to a log file vulnerability. The CWE definition for the vulnerability is CWE-532. Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information. As an impact it is known to affect confidentiality. CVE summarizes:

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. 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. This vulnerability is fixed in Cilium releases 1.11.16, 1.12.9, and 1.13.2. Users unable to upgrade should disable debug mode.

The weakness was released 04/19/2023 as GHSA-pg5p-wwp8-97g8. The advisory is available at github.com. This vulnerability was named CVE-2023-29002 since 03/29/2023.
