However, if there is any flaw in it, the hacker can bypass the authentication and break the security. Generally, this type of attacks occurs due to improper implementation of authentication and session management such as:

Poor login credentials

– Authentication credentials are not secured or unencrypted.

– Credentials such as passwords and session IDs being sent over unencrypted connections

– No session timeout

– Validating the session value even after logout.
