DescriptionNVD

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Starting in version 1.14.0 and prior to versions 1.14.16 and 1.15.10, a policy rule denying a prefix that is broader than /32 may be ignored if there is a policy rule referencing a more narrow prefix (CIDRSet or toFQDN) and this narrower policy rule specifies either enableDefaultDeny: false or - toEntities: all. Note that a rule specifying toEntities: world or toEntities: 0.0.0.0/0 is insufficient, it must be to entity all.This issue has been patched in Cilium v1.14.16 and v1.15.10. As this issue only affects policies using enableDefaultDeny: false or that set toEntities to all, some workarounds are available. For users with policies using enableDefaultDeny: false, remove this configuration option and explicitly define any allow rules required. For users with egress policies that explicitly specify toEntities: all, use toEntities: world.

AnalysisAI

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Incorrect Default Permissions (CWE-276), which allows attackers to access resources due to overly permissive default settings. Cilium is a networking, observability, and security solution with an eBPF-based dataplane.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Set restrictive default permissions, follow principle of least privilege, review defaults during deployment.
