CVE-2023-28614Network attack vector

Unauthenticated remote code execution via shell metacharacters

Published Sep 15, 2023 · Updated Sep 25, 2024

OS command injection in Freewill iFIS 20.01.01.04 allows remote attackers to execute arbitrary shell commands via a report page. The application passes a user-controlled report parameter directly to shell_exec, allowing shell metacharacters to append attacker commands. Access to the web interface requires no authentication, and successful execution can fully compromise the application host.
