Folks,
According to The Register, today, there's a serious vulnerability in all versions of Joomla from 1.5 to 3.4.5. It's being exploited now.
The story is at
www.theregister.co.uk/2015/12/15/joomla_vuln/
The main recommendation is to upgrade to 3.4.6. I've just done 3.4.5 to 3.4.6 on the Inner London web site and it went smoothly.
All the best.
Phil (Chair, Inner London Area)
