CVE-2022-27905

Local privilege escalation via unquoted process path

Published Apr 27, 2022 · Updated Aug 3, 2024

Unquoted path handling in ControlUp Real-Time Agent before 8.6 allows local users to execute code with elevated privileges. The agent passes an unquoted executable path to CreateProcessAsUserA, allowing Windows to resolve an attacker-controlled executable first. Exploitation requires write access to C:\ and the ability to restart the cuAgent service, after which the planted code runs with the service's privileges.
