Security issue: Remote Command Execution with Privileged Escalation

FreePBX with the following versions(or less than) of the specified modules have the potential for remote command execution that can result in privileged escalation:

< userman v13.0.76.43
< userman v14.0.7
< userman v15.0.20
< sysadmin v13.0.92
< sysadmin v14.0.38.3
< sysadmin v15.0.13.6

This has been fixed in:
>= userman v13.0.76.44
>= userman v14.0.8
>= userman v15.0.21
>= sysadmin v13.0.93
>= sysadmin v14.0.38.4
>= sysadmin v15.0.13.7
