Remote Access Management service/API (RPC server) Elevation of Privilege Vulnerability

Improper authentication in Windows RPC API allows an unauthorized attacker to elevate privileges over an adjacent network.

FAQ

According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?

This vulnerability's attack is limited at the protocol level to a logically adjacent topology. This means it cannot simply be done across the internet, but instead needs something specific tied to the target. Good examples would include the same shared physical network (such as Bluetooth or IEEE 802.11), logical network (local IP subnet), or from within a secure or otherwise limited administrative domain (MPLS, secure VPN to an administrative network zone). This is common to many attacks that require machine-in-the-middle (MITM) type setups or that rely on initially gaining a foothold in another environment.

According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?

To trigger this vulnerability, a user must actively connect to the affected server and run a specific command. The vulnerability cannot be triggered automatically or in the background; it only occurs when a user intentionally interacts with the server using this command.

What privileges could be gained by an attacker who successfully exploited this vulnerability?

An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.
