Security researcher from Government Lab Mohammed Adel has found a vulnerability in the UK Defence Gateway that exposes army data. He exploited the vulnerability in a kind of Filtering Bypass attack. Adel was able to access the private lessons that the Defence Gateway delivers to its staff. The Government Lab rated the bug 6.2 over 10.2. The vulnerability is classified as a classified issue, but the vulnerability is kind of a ‘filtering bypass attack and redirect files A hacker can access the information and sell it to threat actors.”]
