pomelo-monitor through 0.3.7 is vulnerable to Command Injection.It allows injection of arbitrary commands as part of 'pomelo-monitor' params.

Pomelo v2.2.5 allows external control of critical state data. A malicious user input can corrupt arbitrary methods and attributes in template/game-server/app/servers/connector/handler/entryHandler.js because certain internal attributes can be overwritten via a conflicting name. Hence, a malicious attacker can manipulate internal attributes by adding additional attributes to user input.
