Cachet vulnerable to new line injection during configuration edition

Impact

Authenticated users, regardless of their privileges (User or Admin), can exploit a new line injection in the configuration edition feature (e.g. mail settings) and gain arbitrary code execution on the server.

Patches

This issue was addressed by improving UpdateConfigCommandHandler and preventing the use of new lines characters in new configuration values.

Workarounds

Only allow trusted source IP addresses to access to the administration dashboard.
