Nssm-2.24 Privilege Escalation [exclusive] -

NSSM allows a standard user (without admin rights) to install a service, but here lies the critical catch: on Windows. You cannot simply run nssm install from a command prompt as a standard user and succeed. Or so the logic goes.

: The attacker checks Windows services to find binaries running with elevated privileges (like LocalSystem or NetworkService ). They identify a service utilizing NSSM-2.24.

The is a classic example of an unquoted service path vulnerability leading to full system compromise. It highlights the importance of not just using reliable tools, but configuring them correctly. By ensuring service paths are quoted and keeping software updated, organizations can easily mitigate this threat. Need to check your systems? nssm-2.24 privilege escalation

To understand the full impact, it is useful to map the known vulnerabilities across different software implementations: NSSM allows a standard user (without admin rights)

If the output says 2.24 , the system is vulnerable.

Historically, multiple notable CVEs (such as CVE-2016-8742 in Apache CouchDB and CVE-2025-41686 in Phoenix Contact Device and Update Management ) have been registered because wrappers around NSSM failed to restrict system modifications. Primary Vectors for NSSM-Based Privilege Escalation : The attacker checks Windows services to find

The for CVE-2025-41686 and CVE-2016-20033 reflects the ease of exploitation (Low Attack Complexity, Low Privileges Required) and the severe consequences. CVE-2024-51448, with a score of 6.7 (Medium), is less severe because it requires an attacker to already have "High" privileges to exploit it, though it still enables a jump to Administrator.
