However this morning Vodafone UK released a statement confirming that the company had been aware of the vulnerability for some time and had taken action in early 2010 to rectify the problem.
'The claims regarding Vodafone Sure Signal, which is a signal booster used indoors, relate to a vulnerability that was detected at the start of 2010. A security patch was issued a few weeks later automatically to all Sure Signal boxes,' a Vodafone UK spokesperson said.
'As a result, Vodafone Sure Signal customers do not need to take any action to secure their device.'
Recently two Australian telco providers began trialling the devices, with Optus launching a limited consumer trail in select areas of New South Wales and Queensland earlier in the year and Vodafone quietly launching their own Femtocell trial program for businesses around the same time.
Vodafone Hutchison Australia confirmed this afternoon that customers involved in their Femtocell program are not impacted by the vulnerability, while an Optus spokesperson said that their '3G Home Zone' customers use a different version and network configuration that isn't susceptible to the exploit.
