Authenticated command execution via Velocity template evaluation
Published Mar 18, 2024 · Updated Mar 25, 2025
Server-side template injection in Komm.One CMS 10.4.2.14 allows remote authenticated users to execute operating-system commands. A crafted /site/node URL is evaluated as Apache Velocity syntax, allowing a template expression to resolve java.lang.Runtime and invoke getRuntime().exec with an attacker-chosen command. Low-privileged access and a reachable affected node are required; command output is returned in the HTTP response, exposing the CMS host to full code execution.
