Because NSSM is a legitimate utility, its presence on a system does not automatically trigger alarms for many security products. However, this very property makes it attractive to attackers who wish to blend in with normal administrative activity.
The vulnerability is located in the service.c file, within the nssm_config function. The function reads the service configuration file and parses its contents without proper validation. An attacker can exploit this by creating a malicious configuration file containing specially crafted commands, which will be executed by the service manager.
This paper presents an analysis of a critical vulnerability in NSSM-2.24, a popular service manager for Windows. The vulnerability, which allows for privilege escalation, was identified and verified through a thorough examination of the software's source code and behavior. A proof-of-concept exploit is provided to demonstrate the vulnerability's impact, along with recommendations for mitigation and patching.
The version 2.24 release introduced support for environment variable configuration and improved logging capabilities. However, this same version also carried several known functional bugs that later informed security researchers' understanding of its attack surface.
