  name: Weaver E-mobile client.do - Remote Code Execution
  author: SleepingBag945
  severity: critical
  description: |
    E-Mobile 6.0 has a command execution vulnerability. It has now been confirmed that this vulnerability can be exploited by an attacker. In some cases, user input may be passed directly to the command execution function of the underlying operating system. An attacker can insert special characters or Command sequence to trick the application into executing it as a valid command, thus gaining command execution permissions from the server.
