Nssm-2.24 Privilege Escalation
: Use tools like icacls to verify that the "Users" group does not have "Full Control" over service binaries.
If the attacker has write access to the service configuration (often misconfigured in legacy systems), they can proceed.
: Windows will attempt to find and execute files along the path in order. For example, it might try to run C:\Program.exe nssm-2.24 privilege escalation
: A more recent vulnerability identified in products like Phoenix Contact Device and Update Management involves misconfigured permissions on nssm.exe specifically, allowing low-privileged local attackers to gain administrative access. Vulnerability Summary Table CVE-2016-8742 Detail - NVD
NSSM is an open-source service helper. Unlike the native Windows sc.exe , NSSM provides a user-friendly interface and robust monitoring features. It is frequently used in development environments and by DevOps teams to manage web servers, database proxies, and custom scripts as background services. The Core of the Vulnerability: Insecure File Permissions : Use tools like icacls to verify that
Run the following command to correct permissions on your service folder:
The Non-Sucking Service Manager (NSSM) is a popular, open-source utility used by system administrators to run command-line applications as Windows services. While it simplifies background process management, older versions contain critical vulnerabilities. Specifically, issues surrounding NSSM version 2.24 frequently expose systems to privilege escalation attacks. For example, it might try to run C:\Program
The Non-Sucking Service Manager (NSSM) is a lightweight, open-source utility designed to simplify the creation and management of Windows services. Unlike Microsoft's built-in sc command or legacy tools like srvany , NSSM offers a more robust solution, automatically handling restarts for crashed applications and providing detailed logging. It is particularly favored by developers and system administrators for wrapping any standard executable (console apps, scripts, Java JARs, Node.js servers) into a fully-fledged Windows service.
Look for nssm.exe in the path or the Parameters\Application registry key.
