Any local unauthenticated attacker could potentially exploit this flaw. This major crucial issue can even lead to a chat buffer overflow and also lead to many unknown impacts as well that would stand as a threat to the dignity of the airlines.

This flaw is not an ordinary one and is something that cannot be overlooked as apart from triggering a buffer overflow, the flaw can also lead to a crash in the application of the entertainment system of the airlines.

Hector Marco Gisbert, who holds the position of associate professor in Cybersecurity and Networks at the University of West Scotland, is of the view that carrying out a potential attack on the application through the use of just the mouse is quite a time taking the task. He further states that the use of ASCII acts as a challenge to create a working ROP attack on the applications.
