What the vulnerability does

01Description

OpenHarness prior to commit dd1d235 contains a command injection vulnerability that allows remote gateway users with chat access to invoke sensitive administrative commands by exploiting insufficient distinction between local-only and remote-safe commands in the gateway handler. Attackers can execute administrative commands such as /permissions full_auto through remote chat sessions to change permission modes of a running OpenHarness instance without operator authorization.
