Using a specific password within FreeRADIUS user management causes pfSense to restore a backup!
I have noticed some really strange behaviour when using a specific password for a freeradius user account. Somehow I can't use the password 'W!f!4c3ss.' (without the quotes).
Everytime I enter the mentioned password and click on save the WebGUI shows "01 unread notice" - "Acknowledge All Notices" - "[pfSense is restoring the configuration /cf/conf/backup/config-1425739xxxx.xml]". The changes are then not getting applied (checked within /usr/pbi/freeradius-amd64/local/etc/raddb/users). Every other password works. I guess there is something wrong with the way the input gets parsed.
This seems independent of the browser in use. Tested with Chrome (40.0.2214.115 m) and Internet Explorer 11 (11.0.9600.17631).
