Description

Advanced Installer before 22.6 has an uncontrolled search path element local privilege escalation vulnerability. When running as SYSTEM in certain configurations, Advanced Installer looks in standard-user writable locations for non-existent binaries and executes them as SYSTEM. A low-privileged attacker can place a malicious binary in a targeted folder; when the installer is executed, the attacker achieves arbitrary SYSTEM code execution.
