I just found that if logging is enabled on YubiRADIUS, Active Directory passwords are written to the log file. This is a extremely serious security oversight. Passwords should NEVER be written in clear-text anywhere. We were not planning to have logging on under production use, but even the possibility that passwords could leak into logs makes the use of YubiRADIUS a non-starter for us.

Hello,

Can you please confirm the version of the YubiRADIUS you are using? This issue was addressed in the recent version YubiRADIUS 3.6.1.

Thanks and best regards,
Samir.

We are using version 3.6.1. The passwords are logged in /var/log/freeradius/radius.log when I enable logging in the Global Configuration >> FreeRADIUS page.

Hi,

we have the same problem. The radius.log is looking like this, with Active Directory Auth
my Passwort for XXXXXXXXXXXXX ;-)

So is there a way to stop freeradius to write down the userpasswords without deaktivation logging. (at least on trouble shooting i will need a log, but never want or need to know any user passwords)
Also in the Troubleshoot Menu i can see the password.

Thanks for you help
Tobias
