What is CVE-2020-11492?

A local privilege escalation vulnerability exists in Docker Desktop on Windows, where a local attacker can create a named pipe with the same name as that used by Docker. If this occurs before Docker starts, the attacker can intercept connection attempts from the Docker Service, which operates with elevated SYSTEM privileges. This interception allows the attacker to impersonate the Docker service, potentially leading to unauthorized access and control over the system resources and operations. It highlights the importance of securing named pipes and the need for stringent access controls on services running with high-level privileges.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
