X-IO Technology ISE Bad Password Immediately After Reset

We installed a rack of X-IO ISE 200, and 800 series SAN shelves for POC testing purposes this week. A random password was generated to replace the default and stored in our password safe as is our procedure. Unfortunately immediately after setting this password we could no longer log in with the new one, nor the default! A bit of hammering led me to discover that this was caused by the random password containing a backslash character. As soon as I removed the backslash and attempted to log in the password worked again. Apparently the set password routine stripped the backslash (probably sanitizing input) and set the password, while the login routine treated it as a valid password character. Could that mean that the authentication fields are not sanitized at all? I hope little Bobby Tables doesn't try to log in...
