What is CVE-2025-23222?
CVE-2025-23222 is a high-severity vulnerability in Deepin dde-api-proxy, published on 24 Jan 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
An issue was discovered in Deepin dde-api-proxy through 1.0.19 in which unprivileged users can access D-Bus services as root. Specifically, dde-api-proxy runs as root and forwards messages from arbitrary local users to legacy D-Bus methods in the actual D-Bus services, and the actual D-Bus services don't know about the proxy situation (they believe that root is asking them to do things). Consequently several proxied methods, that shouldn't be accessible to non-root users, are accessible to non-root users. In situations where Polkit is involved, the caller would be treated as admin, resulting in a similar escalation of privileges.
