: The attacker locates the nssm.exe binary installed as part of the DaUM-WINDOWS-SERVICE with improperly configured permissions that allow modification or replacement by non-administrative users.
The attack vector is straightforward:
To mitigate the NSSM-2.24 exploit, users should upgrade to a newer version of NSSM that is not vulnerable to the exploit. NSSM version 2.26 and later versions have been patched to fix the vulnerability. nssm-2.24 exploit
The NSSM-2.24 exploit refers to a specific vulnerability in the Non-Sucking Service Manager (NSSM) version 2.24. NSSM is a service manager for Windows that allows users to easily install, configure, and manage services on their systems. While NSSM is a popular and widely-used tool, the 2.24 version has been found to contain a critical vulnerability that can be exploited by attackers.
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. : The attacker locates the nssm
The exploit takes advantage of a flaw in the way NSSM handles service configuration files. Specifically, the vulnerability occurs when NSSM attempts to load a service configuration file from a directory that is not properly secured. An attacker can exploit this vulnerability by creating a malicious service configuration file and placing it in a directory that NSSM will load from.
