Local privilege escalation via unquoted service path
Published Jul 15, 2021 · Updated Aug 4, 2024
Unquoted service paths in Zscaler Client Connector before 2.1.2.150 allow local users to execute code with SYSTEM privileges. The Windows service registration leaves an executable path containing spaces unquoted, so Windows can launch an attacker-planted executable from an earlier path segment. Exploitation requires local low-privileged access and control of a writable directory along that path; successful code execution inherits SYSTEM privileges.
