Nssm-2.24 Exploit Upd Jun 2026

Update to the latest version, verify binary file permissions, and ensure service paths are enclosed in quotes if they contain spaces. Use cases - NSSM - the Non-Sucking Service Manager

is a concrete example. This vulnerability, which carries a CVSS score of 7.8 (High) , arises from improper permissions set on the nssm.exe file. A low‑privileged local attacker can overwrite or replace nssm.exe with a malicious binary. When a higher‑privileged process (or a service) later executes the manipulated NSSM file, the attacker’s code runs with administrative rights, leading to full system compromise.

Exploit code for CVE-2016-20033 is publicly available on platforms including Exploit-DB and Zero Science, though active exploitation in the wild remains unconfirmed. nssm-2.24 exploit

The NSSM-2.24 vulnerability highlights the importance of thorough vulnerability analysis and responsible disclosure. By providing a proof-of-concept exploit and recommendations for mitigation, this paper aims to contribute to the development of more secure software and protect users from potential attacks.

In Wowza Streaming Engine version 4.5.0, the nssm_x64.exe binary located in the manager and engine service directories was discovered to have improper file permissions that granted "Everyone" group full access. This misconfiguration allowed any authenticated local user to replace the legitimate nssm.exe with a malicious executable that would execute with LocalSystem privileges when the service restarted. Update to the latest version, verify binary file

The exploit specifically targets a vulnerability in the nssm-2.24 version, which allows an attacker to escalate privileges from a low-integrity process to a higher integrity process. This could potentially allow an attacker to gain elevated privileges on a system, leading to a compromise of the system's security.

The following is a hypothetical example and should not be used for malicious purposes. It illustrates a conceptual approach to exploiting a vulnerability and is not directly applicable to the nssm-2.24 exploit: A low‑privileged local attacker can overwrite or replace

Always ensure service paths are quoted in the registry to prevent unquoted path attacks.

to create and manage malicious services on compromised hosts. Securelist Recommendation

A proof‑of‑concept exploit has been publicly demonstrated (e.g., in a script simulating CVE‑2025‑47968) that uses NSSM to install a malicious service and then escalate to SYSTEM privileges:

int main() // Create a malicious configuration file FILE* config_file = fopen("C:\\path\\to\\nssm-2.24\\test.conf", "w"); fprintf(config_file, "[test]\n"); fprintf(config_file, "binPath= C:\\path\\to\\malicious\\payload.exe\n"); fclose(config_file);
