A closely related vulnerability, , was disclosed in IBM’s Robotic Process Automation (RPA) product. IBM RPA versions 21.0.0 through 21.0.7.17 and 23.0.0 through 23.0.18 allow a local user to escalate privileges because “all files in the install inherit the file permissions of the parent directory and therefore a non‑privileged user can substitute any executable for the nssm.exe service.” This highlights how the same underlying weakness can reappear in different software packages that embed NSSM. Set up SIEM alerts to monitor modifications to

When an administrator uses NSSM to wrap an application (like a Java app, Python script, or binary) into a service, NSSM handles the service start, stop, and monitoring operations. Attackers target NSSM configurations because: IBM RPA versions 21
