Vulnerability Data

A privilege escalation vulnerability exists in Rancher's impersonation middleware (pkg/auth/requests/impersonate.go). An authenticated Rancher user with the default user global role can gain full administrative access to the Rancher control plane and transitively to all downstream clusters it manages. This issue…

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations for logical access, directly stopping unauthorized actors from reaching sensitive system information.

AC-16 Security and Privacy Attributes good match

Associating and preserving security attributes such as original source identity prevents the loss of provenance that creates the confused deputy.

AC-4 Information Flow Enforcement good match

Information flow enforcement requires preserving and checking source attributes before forwarding requests outside the trust boundary.

AC-6 Least Privilege good match

Limits privileges so that only the minimum necessary access is granted, reducing the chance of exposing system-level details.

SC-7 Boundary Protection partial match

Boundary protection limits and inspects external forwarding, reducing the ability of an intermediary to act as an unintended proxy.

PR.AA-04 mostly match
prevents

Proper conveyance and verification of original identity assertions directly prevents loss of request source when forwarding.

PR.AA-05 mostly match
prevents

Enforcing least-privilege access permissions directly prevents unauthorized actors from reaching sensitive system information.

PR.IR-01 mostly match
prevents

Protecting environments from unauthorized logical access stops exposure of internal system details to outsiders.

PR.PS-06 partial match
prevents

Secure-development practices reduce the chance of code paths that leak sensitive system information.

A.5.15 Access control partial match
prevents

Access-control rules can limit which upstream identities may cause the product to act on their behalf, reducing confused-deputy risk.

A.5.16 Identity management partial match
prevents

Proper identity management ensures the original requester identity is preserved and validated before the product forwards requests.

A.5.18 Access rights partial match
degrades

Explicit access-rights assignment can restrict the product’s ability to act as an unintended proxy for external actors.

A.8.2 Privileged access rights partial match
degrades

Privileged-access controls limit the rights the product may exercise on behalf of upstream callers, mitigating confused-deputy abuse.

A.8.20 Networks security partial match
degrades

Network-security controls can enforce source validation and prevent the product from blindly proxying traffic to external actors.

A.8.25 Secure development life cycle partial match
prevents

Secure-SDLC practices include design reviews that detect and eliminate confused-deputy proxy patterns before deployment.
