This newly discovered bugs in Java and Python is a big deal today.
The two popular programming languages, Java and Python, contain similar security flaws that can be exploited to send unauthorized emails and bypass any firewall defenses.
And since both the flaws remain unpatched, hackers can take advantage to design potential cyber attack operations against critical networks and infrastructures.
The unpatched flaws actually reside in the way Java and Python programming languages handle File Transfer Protocol (FTP) links, where they don’t syntax-check the username parameter, which leads to, what researchers call, protocol injection flaw.
