CVE-2020-4428Known exploitationPublic exploitNetwork attack vector

Command execution via uploaded nmap script

Published May 7, 2020 · Updated Nov 3, 2025

OS command injection in IBM Data Risk Manager 2.0.1 through 2.0.4 allows remote authenticated users to execute arbitrary commands. The nmap scan API passes an attacker-controlled ipAddress value to nmap, allowing a previously uploaded NSE script to be selected with --script and executed. Administrative authentication and patch-file upload access are required; successful exploitation runs commands as the appliance server account.
