Nssm224 Privilege Escalation Updated Access

The vulnerability arises when a service installed using NSSM has an executable path that contains spaces and is not enclosed within quotation marks. 1. The Root Cause: Unquoted Service Paths

The "Privilege Escalation Updated" tag comes after a proof-of-concept exploit demonstrated that the flaw doesn't just crash the service—it manipulates the recovery mechanism. By injecting a malicious payload into the service’s failure command flag, an attacker with low-level access can force the application to execute arbitrary code with SYSTEM privileges. nssm224 privilege escalation updated

If exploiting , the attacker modifies the registry path using reg.exe : The vulnerability arises when a service installed using

NSSM allows users to install a service that does not have native Windows service support. Its key feature is that it runs as SYSTEM (the highest privilege level on Windows) by default when installed as a service. By injecting a malicious payload into the service’s

Until then, variants will continue to appear in red team toolkits. The responsibility falls squarely on defenders to audit service permissions and restrict NSSM execution.
