CVE-2020-8655Known exploitationPublic exploit

Root command execution via unrestricted nmap scripts

Published Feb 6, 2020 · Updated Oct 21, 2025

Privilege escalation in EyesOfNetwork 5.1 through 5.3 allows local users to execute arbitrary commands as root through a crafted NSE script. The default sudoers entry permits the apache account to invoke /usr/bin/nmap without a password, and nmap loads attacker-written NSE code with root privileges. Exploitation requires control of the apache service account and grants complete host control; a public exploit chains web-interface flaws to obtain that context remotely.
