A serious security flaw has been found in one of the most widely used tools in schools, which could leave hundreds of thousands of children's personal information exposed to hackers.
The tool, Impero Education Pro, is a product that restricts and monitors students' website use and is used in 275 of UK secondary schools.
Security researcher Zammis Clark last month posted extensive details of a flaw in the company's encryption protocols, which could allow almost anyone to gain full access to computers running the software.
The company has released a temporary security patch and is currently working on a permanent upgrade.
Clark believes the flaw will leave the networks' security fully compromised and information rendered on it would be vulnerable.
Clark posted his findings publicly rather than privately, which is a controversial practice in the world of online security. Some people believe private disclosure is better initially, as it gives companies time to fix flaws before they are made public.
Impero's Education Pro software serves a variety of roles in schools' systems including blocking inappropriate web surfing such as adult sites and monitoring students' activity as well as rationing printing and making IT administration simpler.
