Technical details
OS command injection in the username field of login.lua, cleanout.lua, and api.lua occurs before authentication is performed. The vulnerability is pre-authentication (no login required) and network-accessible; shell metacharacters injected into the username are executed by a setuid-root wlua interpreter, allowing arbitrary code execution with elevated privileges. The flaw affects versions 5.2.3 through 5.6.x, with a fix available in version 5.7.0 and later.
