Privilege Escalation in Deepin dde-api-proxy D-Bus Forwarding
CVE-2025-23222 affects Deepin dde-api-proxy through 1.0.19. The proxy runs as a root-privileged system D-Bus service and forwards requests from arbitrary local users to legacy D-Bus methods implemented by backend services. The flaw is that dde-api-proxy performs forwarding without preserving or revalidating the original caller’s authorization context. As a result, backend D-Bus services receive proxied requests as if they originated from root rather than from the unprivileged local user. This breaks the trust boundary between the caller and the privileged service and exposes methods that should not be available to non-root users. Where Polkit authorization is involved, the backend may evaluate the request as coming from an administrative caller, leading to the same privilege-escalation outcome.
