CVE-2020-7954

Root command execution via passwordless sudo nmap

Published Feb 6, 2020 · Updated Aug 4, 2024

Privilege escalation in OpServices OpMon 9.3.2 allows local users with the apache account to execute commands as root via sudo. The default server sudoers configuration grants the apache account passwordless sudo access to nmap, whose interactive features permit command execution. Control of the apache service account is required; successful exploitation provides root-level control of the OpMon server.
