A penetration tester gains access to a host with many applications that load at startup...

The scenario highlights a Windows host where “many applications load at startup and run as SYSTEM,” which points directly to Windows services and auto-start components executing with high privileges. In PenTest+ privilege escalation techniques, unquoted service path injection is a common and effective method when a service runs as SYSTEM and its executable path contains spaces but is not enclosed in quotes. Windows may parse the path incorrectly and attempt to execute a malicious binary placed earlier in the interpreted path (for example, C:\Program.exe), as long as the attacker has write permissions to a directory in that search order. This can result in the attacker’s payload being executed as SYSTEM on service start/restart, achieving privilege escalation reliably and with clear evidentiary output.

Credential dumping may help lateral movement, but it does not inherently escalate privileges if the tester already lacks higher-privileged credentials. Local file inclusion is a web vulnerability and not applicable to host startup services. Process hijacking can work in some cases, but unquoted service paths are a specifically documented, high-probability Windows misconfiguration when many SYSTEM services exist.
