O2 has come up with a fix for a flaw that affects some of its home broadband routers.
The cross-site request forgery (CSRF) vulnerability could allow someone to gain unauthorised access to a user's private network. The flaw was first identified by security researcher Paul Mutton, who brought it to the attention of O2 and the router's manufacturer, Thomson.
In a statement on Thursday afternoon, O2 told ZDNet UK:
Having been notified of a potential security issue with our O2 wireless box we have been working to find a solution. We have taken this issue very seriously and have been continuing to investigating it with the router's manufacturer, Thomson.
As a result we have identified a solution and we will be applying this remotely to all of our customers O2 wireless boxes. This means that customers will not have to take any action themselves.
