nssm-2.24 privilege escalation

NSSM 2.24 is a functional tool but requires a secure environment. Its 2.24 version, if not configured with rigid security permissions, provides a significant attack vector for elevating privileges from a standard user to SYSTEM . By securing executable paths and implementing proper permissions, organizations can mitigate this risk.

3. Implement the Principle of Least Privilege for Service Accounts

Securing NSSM 2.24 deployments requires adhering to the principle of least privilege and ensuring rigid access controls. 1. Enforce Strict File and Folder ACLs

The primary method for escalating privileges via NSSM 2.24 involves . If an administrator installs a service using NSSM and the path to the executable contains spaces but no quotation marks (e.g., C:\Program Files\Service Name\nssm.exe ), Windows will search for and attempt to execute files in the following order: C:\Program.exe C:\Program Files\Service.exe C:\Program Files\Service Name\nssm.exe

The most significant and recent vulnerability affecting NSSM is tracked as . This flaw arises from improper permissions set on the nssm.exe executable file, allowing a low-privileged local attacker to escalate their privileges and gain full administrative access to the system.
