IBM Robotic Process Automation 21.0.0 through 21.0.7.17 and 23.0.0 through 23.0.18 could allow a local user to escalate their privileges. 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. A subsequent service or server restart will then run that binary with administrator privilege.
