CVE-2018-25159Public exploitNetwork attack vector

Unauthenticated root command execution via redirect OGNL

Published Mar 11, 2026 · Updated Mar 11, 2026

OGNL injection in Epross AVCON6 allows remote attackers to execute arbitrary commands as root through an unauthenticated login request. The login.action endpoint evaluates the redirect parameter as an OGNL expression, allowing it to instantiate ProcessBuilder with attacker-supplied commands. No credentials or user interaction are required, and successful exploitation returns command output while running commands with root privileges.
